A hacksaw, or as it is also called, a wood saw refers to a tool that should be in every home and even more so in every summer cottage. But the choice of a hacksaw for wood is not as simple as it seems and further, we will analyze in detail the types of tools, you will learn about the configuration and purpose different kinds teeth, let's "walk" through the famous brands, and finally I will tell you what a saber electric hacksaw for wood is and how to choose it.
Hand Tool Specifications
A hand saw for wood has several fundamental parameters - this is the steel grade, blade length, blade shape and handle inclination, but the most important parameter is the shape and type of the tooth, and this characteristic is the same for both manual and electric models.
The quality of domestic hacksaws for wood is in no way inferior to foreign counterparts
Hacksaw blade length
It all depends on the purpose for which the hacksaw is being bought. So if you take a hacksaw in city apartment and do not plan to work with it constantly, then a folding model with a blade length of 300 - 400 mm is quite enough. For a private house or summer cottage, you already need a full-size tool with a canvas of 500 - 700 mm.
Important! When cutting a workpiece, the length of the blade should be at least twice the thickness of the workpiece, otherwise sawdust will accumulate inside the cut and the hacksaw will quickly jam.
For one-time work, folding or small-sized types of hacksaws for wood are suitable
Steel grade for hacksaw for wood
In the recent past, hacksaws were made from grades HRс45 and HRс50, the metal is of high quality, but the blade requires periodic sharpening. Now all the leading manufacturers produce hacksaws with combined blades.
The blade itself is made of HRc45 steel, which provides it with good flexibility and high strength, and the cutting edge with teeth is made of HRc55 or HRc60 steel. You can recognize these hacksaws by the dark cutting edge.
Important! When purchasing a dark-edged, high-strength steel hacksaw, make sure it is already set and sharpened properly. The fact is that sharpening and wiring by an amateur of such metal at home is very problematic, so you will have to pay extra for sharpening the canvas.
Wood hacksaws with dark cutting edges are of high quality
Choosing a tooth for a hacksaw for wood
Before we deal with the tooth configuration, let's talk about the marking and the size of the teeth. All types of wood hacksaws are classified according to the same parameters. The marking indicates the number of teeth per 1 inch (1`` = 25.4 mm) and denotes this indicator as TPI.
TPI indicates the number of teeth per inch of blade
- A hacksaw for wood with a fine tooth has a TPI of 7 and above. And what more number TPI, the more accurate and cleaner the cut will be, but at the same time, the speed of work with such a tool decreases in proportion to the increase in TPI, in other words, a small tooth cuts accurately, cleanly, but for a long time;
- A hacksaw for wood with a large tooth has a TPI of 1 to 7. A similar tool is intended for work on garden and summer cottages, in other words, a large tooth is taken to cut wood or cut branches.
The higher the TPI in the marking, the cleaner and smoother the cut in wood.
There is a common expression "middle tooth", and so in the documents the value of the TPI of the middle tooth is not fixed anywhere, but the people refer to this direction as hacksaws with TPI from 5 to 8.
Tooth pitch is far from the only parameter when choosing a hacksaw
| Hacksaw tooth diagram | Explanation |
 |
.
Made in the form of an isosceles triangle, sharpened on both sides. |
 |
.
Here the triangle is chamfered towards the cut and the cutting edge of the tooth becomes perpendicular to the wood. Sharpening is performed only from the working (perpendicular) side, as a result, the tooth bites into the mass like a chisel. Designed for loosening wood along the grain. |
 |
.
An excellent solution if you buy a hacksaw "for all occasions in life." The triangular tooth is slightly beveled towards the cut, while the sharpening is done on both sides of the tooth. As a result, when cutting along the blade, the tooth works like a chisel, and re-sharpening also allows you to effectively cut wood across the fibers. |
 |
.
This sharpening is sometimes called triangular, but in reality it is not. Most often, a dagger tooth is taken as a basis, but sometimes a universal tooth is also sharpened. The top of the triangle is slightly cut at an angle and additionally sharpened. This approach allows you to work with the tree in any direction and from any angle. |
 |
.
Complex sharpening allows you to do without setting the tooth, but only a professional can do it. The triangular tooth is sharpened on both sides and beveled towards the handle, plus the top is trimmed and sharpened on top. When working with a hacksaw, the cut is made only when the tool is moving towards the worker. The Japanese were the first to use this technology, so the name was taken from there. |
 |
.
Here, several types of teeth are assembled on the canvas at once, but the essence of a wolf's tooth is in the presence of gaps between the sectors. Such a hacksaw is intended for cutting viscous and raw wood, so it is difficult to find models shorter than half a meter.

How to choose a hacksaw for wood
Proven manufacturers of hand saws for wood
- "Zubr"- a domestic manufacturer with a good reputation. Almost all Zubr hacksaws come with a hardened divorced tooth and high-quality sharpening. The company specializes in products with medium and small teeth, but the line includes other models, including those with replaceable blades;
Models of hacksaws with replaceable blades belong to a semi-professional tool
- "Gross Piranha"- here we are dealing with combined hacksaws. The main blade in such a tool is made of flexible HRc52 steel, and the cutting edge with teeth is made of high-strength hardened iron HRc66. The special pride of this brand is the Piranha line of models, which additionally has a Teflon coating and laser tooth sharpening;
Piranha saws with teflon coating and laser sharpening are particularly durable and easy to move.
- Stanley General Purpose- initially this brand belongs to the representatives of the French industry, but now they have opened several subsidiaries in Russia, which made it possible to reduce the price without losing the quality of the product. There is also a basic set, that is, a hardened tooth and laser sharpening. The most popular is the model with the TPI8 step;
French hacksaws have been renowned for their high quality for over half a century.
- Irwin Xpert- models of this brand are of high quality, but compared to the above-mentioned saws, they are almost 2 times more expensive. Although, according to the owners, this tool is worth its money;

There is no priority of certain models, all tools from this brand are of high quality.
Swedish hacksaws produced under the domestic brand "Tescha" are famous for their excellent quality
What is a reciprocating saw and how to choose one
Now let's figure out how to choose an electric woodcutter, in the language of professionals, such a tool is called a reciprocating saw. Compared to hand tools, the selection criteria are slightly different here. So, in addition to the reciprocating motion, the reciprocating saw also has a pendulum motion.
To trim trees with a reciprocating saw, the tool has a pendulum mode of operation
Oscillations of the canvas according to the principle of a pendulum allow you to work much more efficiently, for example, when pruning trees or other rough work. And the standard mode is good for dissolving sheets of different density.
In this case, the question of which hacksaw for wood is better will not be entirely correct, because in reciprocating saws, the effectiveness of the tool depends on the correct choice of the blade. There are blades designed for working on wood, metal, stone, drywall, etc.
Each replaceable reciprocating saw blade is designed to work with a specific material
But the choice of a reciprocating saw does not end only with the purchase of a high-quality blade for the appropriate material, there is also whole line subtleties:
- I, like most masters in this field, believe that buying an electric hacker with a power of up to 600 W is just a waste of money. With it, you can cut branches up to 20 mm in diameter and no more. 600W to 1KW suitable for versatile summer cottage works, and a tool with a power of 1.2 KW is already considered semi-professional and can effectively cut any materials;
- It is advisable to choose a model where a special key is not needed to change the blade;
- It is better to take a tool with a cutting depth stop, which, by the way, can also be adjusted with a key and without a key, respectively, the second type of hacksaws is more convenient;
- Pay attention to the head that holds the blade. There is universal models, into which any canvas is inserted, but there are heads "sharpened" only for branded cloths of this manufacturer. It is not a fact that the store will have the right model of the branded canvas, so take a station wagon;
- Theoretically, all saber saws have the ability to turn off the pendulum stroke, but when buying, it is advisable to check how adequately this option works;
- A reciprocating saw with a travel speed regulator will greatly expand your possibilities in work, and it is desirable that this regulator has a fine tuning function;
- One more useful function the possibility of turning the blade under different angles, this option is especially useful when working on the ceiling and in hard-to-reach, cramped areas;
A reciprocating saw with a battery, in comparison with network models, has less power, but it is more convenient to work with it
Output
Based on the recommendations given above and the video in this article, the competent choice of a hacksaw for wood will become much easier for you and keep in mind that wasted money is not the worst thing, a poor quality tool will take a lot of time and effort, and most importantly, such hacksaws can be dangerous. If there is a desire to add something to what has been said or if you have any questions, welcome to the comments, we will talk.
Almost everyone home master there is a power saw in the work case. But sometimes it is necessary to saw off a part or some woodwork, for which there is absolutely no desire to unfold the device from the suitcase. And in that case, it would be nice to get a hacksaw for wood. Its manual version will be a great helper if necessary. Let's take a closer look at the question of how to choose a hacksaw for wood!
Feature of hand saw for wood
There are many differences in this tool, such as blade sizes, steel grades, the shape of the teeth, as well as the design of the handle itself. Let's consider each of them in more detail.
What should be the blade of a hacksaw for wood
This element is the main parameter of the hacksaw. And the main thing in it is its length. Depending on it, the tool can be used for different purposes. There is one nuance, which is that the longer the blade length, the more the tool springs. This makes it difficult to carve wood, especially if it is necessary to work with maple, oak, ash.
A length of 25-30 cm is quite suitable, if you need to saw small elements of beams, slats, skirting boards. If it is necessary to carry out more serious types of work, then a hacksaw should be chosen with a blade of 45-50 cm.
The basic rule when choosing the length of the canvas is that it must be twice as large as the elements being processed, otherwise it will be more difficult to work. Standard sizes the width of the canvases is up to twenty centimeters. Too narrow models will quickly fail, while wide ones are completely inconvenient to work with.
Hacksaws are made from alloyed tool steel, which contains a lot of carbon and silicon. Standard option the hardness of the material is an indicator of 45 HRC, but for work it is still worth choosing a hardness with an indicator of 55-60 HRC.
Characteristics of the teeth of the hacksaw
It is the size of the teeth that is the most important indicator... Their number per inch shows the TPI, which determines the accuracy of the sawing process. In addition, these parameters are interrelated:
· If the teeth in the blade are large, in this case the speed is high enough, but the cut comes out sloppy.
· If the teeth are small, the working speed is also low, but the saw cut is accurate and very accurate.
When faced with the question of which hacksaw to choose, focus on a TPI of 3-6 for gardening, or 7-9 for chipboard.
The teeth of the hacksaw can be ordinary or hardened. If the tool is used in living conditions, hardened teeth will not dull for a very long time. But when it becomes dull, it will no longer be possible to sharpen it, and the tool will have to be thrown away.
Regular teeth can be sharpened with a file marked with an accident.
There are 3 types of hacksaws, depending on which teeth are used:
To saw longitudinal way
Saw crosswise
Mixed sawing
If you use a modern hacksaw, in which the teeth are trapezoidal, the blade can be made strong and durable. But it is very difficult to sharpen it, which means that there is much less such a product from the rock service.
How to choose a hacksaw? Types and purposes
Narrow saw version
Saw small size, narrow shape, very effective when cutting raw wood. Wet chips very easily come out through the gaps of the teeth, so the movement of the saw is not hindered.
During the manufacture of narrow-shaped saws, their blades have triangular double-sided teeth. The only problem this instrument- its ability to deviate from the desired direction.
It can have absolutely any teeth, as well as a complete set with replaceable blades.
Regardless, these saw options are best used in the furniture manufacturing process.
Saws, in which there is a backing equipment, can be said to have stiffening ribs. But when using hacksaws and increasing the rigidity of the materials that are processed, they can bend. That is why the back is so important. Its main task is to prevent the passage of the cutting blade deep into the wood, for which it controls the depth of cut with the saw so that it is not wider than the blade itself.
Such devices are already more cumbersome. To some extent, they resemble a jigsaw.
To begin with, it is worth deciding on the purpose of using the tool, as well as on the frequency of its use. Decide how even the blade should be, and of course, what cost you are willing to "accept" and buy a hand saw.
Handles are ordinary, plastic. And the presence of a rubberized insert will protect the hands of the master from the formation of corns during the process of wood carving manual option hacksaws.
Your own set of tools seems to be necessary in Everyday life home master. The saw is central to it, as it is irreplaceable when working with wood and its derivatives. Despite the abundance of saws on sale, the most rational solution can be considered the acquisition of a universal variety that can replace numerous analogues in terms of its functionality.
Saw selection
In order to purchase a suitable copy, you need to focus on a number of product parameters, as well as take into account personal preferences. In this regard, visiting the store seems to be a preferable option, since the choice of a hacksaw for wood is difficult without an independent assessment of the convenience of the tool.
Today there is a huge assortment hand saws, which differ from each other both in their characteristics and in design. The last parameter is especially important, since it has a huge impact on performance properties saws.
If the design of the saw assumes the possibility of dismantling and replacing the cutting blade, the consumer has the opportunity to save money when the blade is damaged. In addition, such a design implies the possibility of using a number of canvases in the process of work, each of which has various purposes.
Saw types by blade type
Existing hand saws for wood are distinguished by the type of blade used, because it is the main element of the tool. These categories include:
- Narrow strip designed for through cuts and work in tight spaces. This option is most suitable for simple garden work, as well as sawing workpieces of small thickness. The disadvantages include low performance.
- Standard canvas. It seems to be the best option suitable for the vast majority of jobs. Differs in high cutting accuracy and productivity. The disadvantage is that it is bulky, making storage, use and transportation inconvenient.
- A canvas equipped with a stiffener. Intended to get perfect even cut , which is especially important in the manufacture of furniture and other structures. It does not allow performing a number of works, since the cutting depth is limited by the width of the used blade.
- Onion cloth. Suitable for special saws and has excellent cutting accuracy... Supports edge fastening, as well as the ability to adjust the tension. Large dimensions and design features do not allow deep cuts at an angle.
The type of saw blade should be selected depending on the work that is planned to be performed with it. If the master plans to purchase universal tool, it is advisable to think about purchasing a collapsible design, which will allow you to purchase and use a set of paintings different types.
How to choose the length of the canvas
Considering the range of saws, it is important to consider that universal option along the length of the cutting element does not exist. Short options are distinguished by the possibility of using in conditions of a lack of space, but they have low productivity, which does not allow performing a large amount of work. Long blade is characterized by cutting accuracy and high productivity, but large dimensions do not allow for high accuracy.
Experienced craftsmen recommend following simple rule allowing you to choose optimal length cutting element. It says that the required length is equal to twice the thickness of the largest workpiece used for this class of saws... In this regard, saws are divided into two broad categories, depending on their dimensions.
Products from 20 to 40 centimeters in length are ideal for working with small boards, blanks, slats, as well as for curly cutting. This option is worth buying for gardening, but their performance is low.
Analogs from 45 to 70 centimeters are noticeably more convenient when fully sawing large-sized workpieces, logs, boards and other similar items. To improve the cutting accuracy, it is recommended to use a special butt to prevent the saw from moving during work.
Brand name
Many consumers planning to buy a hacksaw for wood prefer to purchase products from certain brands that have a reputation and guarantee the quality of their products. Among domestic producers it is necessary to mention Izhstal, Ermak, Enkor, as well as a number of others. The main advantage of domestic hacksaws for wood seems to be the relatively low cost even professional models, with high quality products. Izhstal is one of the leaders and is distinguished by the wide range of products.
However, if you need to purchase non-standard saws, you will have to use more expensive products of foreign brands. First of all, this is Bahco, which is famous for its double-sided Japanese-style hacksaws, which allows you to make accurate and accurate longitudinal cuts. Brigadier products have a good combination of price and quality.
Manufacturing material
Since there are many products of unsatisfactory quality on the market, it is recommended to disassemble the materials from which reliable and durable tools... The cutting part is usually made of steel, as this material is better than others for such work. It is highly recommended that its hardness be at least 45 HRC, which will allow you to successfully and safely sharpen the teeth of the tool.
If this figure is lower, the saw will quickly become dull, and the blade will become less elastic. However, the cost of such products is noticeably lower than that of more durable ones, which allows savings in the absence of the need to perform large amounts of work.
It is often possible to buy products, the manufacturers of which have provided for the combined hardening of the tool. This means that the blade itself has a hardness of 45 HRC, and the teeth are more durable - 60. This allows the blade to remain flexible and not break, and the teeth can maintain their sharpness throughout the entire period of operation. It is not recommended to independently set the teeth and sharpen in the absence of special equipment and skills.
Tooth shape
Another important characteristic of the hand saw is tooth shape used for sawing. This parameter is very important, since the purpose of the tool, as well as the productivity of work, depends on it.
There are several of the most common options:
- teeth with acute angle, about 40-50 degrees;
- teeth in the form of equilateral triangles;
- teeth on both sides, leading edge perpendicular to movement.
The last option seems to be the most versatile, since it allows you to work with a wide range of materials and is able to cut the workpiece both along and across the fibers. The performance of such a product leaves much to be desired, however given type teeth allows you to completely replace analogs.
The first type of teeth is distinguished by its ability to perfectly cut workpieces along the grain. Moreover, each of the teeth has two working surfaces at once, which increases productivity. Another feature is the fast removal of even wet sawdust from the cutting area.
The second option is more suitable than others for working with dry wood. It cannot boast of high productivity, and cutting wet wood will require constant cleaning of the tool.
If you need to purchase a truly versatile tool, it is recommended to focus on products whose cutting blade includes several types of teeth at once.
Multifunctional canvases
Today the most popular are universal canvases... Their design is simple and thoughtful: some teeth cut across the fibers of the workpiece, and the second are responsible for cutting along. At the same time, special grooves are located between the groups of teeth, which are responsible for the removal of sawdust. This option is ideal for everyday use, however, there may be problems with sawing accuracy.
There are also a number special tools that are noticeably different from most of their counterparts. These should include primarily furniture saw that does not have jags and allows you to achieve perfect cut smoothness. For long-term operation of this type of saw, it is necessary to perform a special sharpening of the teeth. This option is ideal for working with plywood, chipboard and other materials used in furniture production.
Another exotic option seems to be japanese hacksaw which possesses unique features... Sharpening of teeth is carried out in a similar way to the universal type of saws, however, it is assumed that the movement of the tool during work will be towards the master himself, and not vice versa, as in more traditional options.
Lever
The choice of the handle directly depends on the personal preferences of the master, however, it is permissible to highlight a number of features that will certainly make the work more productive, safe and comfortable.
A quality handle should:
- have an organic shape suitable for the hand;
- be made of modern and durable materials;
- be able to adjust the angle of attachment, which will allow the use of more wide range canvases.
Since each master has his own ideas about the convenience when performing work with a hand saw, more specific recommendations do not make sense. If the handle is correctly selected, productivity will be significantly increased and the hand will be noticeably less fatigued, even when using a shallow saw.
One of the differences between wood and many other building materials is its ease of processing. And, nevertheless, manufacturers produce tools for sawing it in various modifications. What is the difference between this tool, how important it is, how to choose the right hacksaw for wood - this article will help you find answers to all questions on this topic.
Hacksaws for wood are categorized according to the specifics of the application into carpentry and joinery. The tools of the last group are designed for cutting dried wood. They provide a cleaner cut, and precisely along the markings. In other words, the joiner's category hacksaws are chosen for fine work... Carpentry, respectively, for the rough.
Such a tool is used when sawing logs, timber, pruning trees, and the like, that is, in situations where it is not necessary to withstand any certain linear parameters, significant errors in work are allowed or it is enough to cut not according to a template, but "by eye".
Blade length (mm)
This is the first selection criterion. Having not decided on the length, it makes no sense to evaluate all the other parameters of the hacksaw.
There is a generally accepted norm of choice for this indicator, which it is desirable to adhere to. The length of the blade should exceed the size of the overall lumber itself, with which it is supposed to work, approximately 2 times, not less.
Why? Firstly, the teeth of the hacksaw are clogged with sawdust during the sawing process. A two-fold excess of the length ensures that the blade in the extreme positions will completely come out of the wood. As a result, it is self-cleaning due to debris falling off.
Secondly, the greater the amplitude of hand movement when working with the tool, the less they get tired. And this directly affects performance. If a hacksaw is chosen for intensive use, sawing large volumes of wood is more than important.
- If a hacksaw for wood is purchased as a household hand tool, for all cases, 300 blades are enough.
- Overhaul, especially construction, is, among other things, sawing out dimensional samples (log, board,). For such purposes, you should choose a hacksaw with a blade in the range of 475 ± 25.
Steel type
There are many brands of metals. For wood hacksaws, this is typically 45 HRC. The teeth are more difficult. They can be hardened (have a shade darker than the canvas) or without preliminary heat treatment.
Hardened teeth will not stay sharpened. In fact, this hacksaw, although more durable, is in a sense disposable. If, due to negligence, non-observance of the rules of operation, the cutting edges of the tool are dull, then it will not work to bring them into working condition. But for occasional work, small household chores associated with sawing wood - the best option... Choosing a hacksaw from renowned manufacturer, there is no doubt that it will last for a long time.
Unhardened teeth can be sharpened and straightened by yourself. On the one hand, it is convenient and practical. But this requires experience in this matter. How many can boast of them? As a tool for everyday use, it is hardly worth purchasing such a hacksaw. But if it comes about large-scale work with wood (the same construction), then this right choice... Inevitably, you will have to master the basics of sharpening and editing, especially since it is not so difficult.
How to check the quality of steel and sharpening
- You can check the quality of steel without a certificate. The hacksaw blade has a bending limit. Initially, it is perfectly smooth. It is necessary to gently bend it (the hand will “understand” itself when it is ready to break, the permissible extreme position), and then let it go and check the geometry. The deviation of the area subjected to deformation from the centerline by more than 2 mm is an indicator of poor quality of steel. Better to overpay, but choose another hacksaw for wood.
- The type of teeth can be determined visually. If they are of a traditional, triangular configuration, then the hacksaw must be straightened and sharpened. Trapezoidal cutting edges - hardened. They have already been mentioned above.
Tooth size
This characteristic of the hacksaw is displayed on the blade with TPI symbols. The dimension of the quantity is the number of teeth / inch.
As a rule, craftsmen are interested in 2 indicators of the efficiency of sawing wood - the speed and accuracy of the cut. The point is that these parameters are in inverse relationship... The cleanliness of the cut is ensured fine teeth, but this reduces the speed of cutting the material. And vice versa - a hacksaw with large cutting edges produces a cut at a higher speed, but its accuracy deteriorates.
- 3 - 6. This hacksaw is suitable for rough woodworking. For example, cutting large branches on the site, sawing small-sized logs, boards, and so on. That is, in cases where the presence of fringe on the edges is uncritical, and cutting accuracy is not a defining requirement when working with wood.
- 7 - 9 and more. It is advisable to choose this type of hacksaw when you plan to work with sheet materials- Particleboard, MDF, OSV, FC and so on. Such a tool will provide a "delicate" cut, after which there is no fringe and torn edges.
Hacksaw handle type
- Check if it is comfortable in your hand. The main difference between the hands of people is in size. The solution is simple - take a hacksaw in the palm of your hand, squeeze your fingers and make a few forward movements. A man will immediately understand whether "his" is a tool or it is better to choose something else.
- The handles of hacksaws for wood are classic (cast) and swing-over. The first allows the replacement of the blade.
And here it is more interesting. If you choose a hacksaw with a cross over handle, then it makes sense to purchase a product with a "disposable" blade with hardened teeth. Even in the case of careless handling of the instrument, it can be “repaired”. It is only necessary to clarify whether it is on sale (it is in this point of sale or another in this locality) replaceable blades and whether they are in short supply. When buying a hacksaw for small chores, it is enough to take 1 spare. Considering the increased wear resistance of the teeth and their strength, such a "set" will be enough for many years.
There is a relationship between the size of the teeth and their location. "Step" of three adjacent cutting edges should be less than the section of the cut wood blank... This is easy to calculate if a hacksaw is chosen for sawing boards or small blocks, that is, for everyday work, which is most often encountered in everyday life.
The cutting method depends on the type of teeth sharpening. Longitudinal blades have a length of up to half a meter, a greater inclination of the cutting edges to the side and their one-sided sharpening. Sawing with such a hacksaw is carried out only in the direction "away from you". This tool is quite specific and as a household tool, you should not choose it for everyday use.
Hacksaws for wood with a transverse blade are considered universal. Sawing is done both forward and backward. Such a tool can be easily identified by double-sided sharpening of cutting edges.
A quick overview of the most purchased wood saws
This TOP list is based on the results of the analysis of reviews, opinions posted on thematic forums. To say that they are the only true ones would not be entirely correct. But it is hardly worth ignoring them completely. If people in practice used one or another hacksaw for wood, then it makes sense to listen to their assessments. And then finally decide which one to choose.
All prices are in Russian rubles, for the Moscow region.
"Zubr Expert"
Such a hacksaw for wood, taking into account the reasonable price and versatility, is in high demand. Hardened triangular teeth, plastic handle, both longitudinal and transverse cut. The range is impressive. Big choice hacksaws of this brand in terms of TPI and blade length allows you to purchase the best option.
Price - from 738 (canvas 40 cm).
Stanley General Purpose
A hacksaw from a French manufacturer is 0.5 m long, hardened teeth with TPI = 8. The wood is cut in any direction. For a private house or summer cottage - an excellent choice.
Price - 849.
"Gross Piranha"
This hacksaw is available on the market in different modifications. Differences in the number of cutting edges and blade length (400 - 550). The quality of the steel (52 HRc) is further enhanced by a Teflon coating that makes the cutting process easier. In addition, a near-perfect edge cleanliness is achieved.
Price - from 913.
Irwin Xpert
The main characteristics are identical to the hacksaw of the previous brand, although the cost is slightly higher. Users check high quality and ease of cutting, regardless of the density of the wood. Even when cutting hard wood, no significant effort is required. Those who have to regularly work with lumber in everyday conditions should pay attention.
Price - from 705.
"Bahco"
Previously, these hacksaws for wood were sold under the Sandvik logo, so they are known to many. Production has been established at several sites, and in the Russian Federation these samples are more often imported under the "Mother-in-law" brand. The cost is lower, while the quality remains high. Bahco hacksaws belong to the group of professional tools, which is hardly advisable to choose for petty work with wood. But the cheaper products "Mother-in-law" are just right for those who wish to save reasonable money.
Price - from 389 (360 mm).
About what criteria should be used to evaluate a hacksaw for sawing wood, it is described in detail, the main recommendations are given. And what exactly to choose is up to you, dear reader.
Wood has been used as a building material since time immemorial. And now it has not lost its popularity. He is loved for ecological cleanliness and ease of processing, which is best done with a hacksaw for wood. These tools are available with different parameters, which are selected depending on the specific application.
Specifications
Saw - one of the first hand tools invented by man. Centuries have passed since the first rough version appeared, and many varieties have appeared for different types of work.
As for hand saws for wood, they differ among themselves in many parameters, including the following:
Let's consider each in detail.
Hacksaw blade
In principle, this is the instrument itself. The most important parameter the length of the canvas is. It is she who determines the range of application possibilities. However, the longer the blade, the stronger the spring, which makes it especially difficult to work with hard rocks woods like oak, ash or maple. For cutting small objects such as a plinth, a bar or a narrow strip, a hand hacksaw for wood with a blade length is enough 25-30 cm... For more serious work, you need a tool with a blade length 45-50 cm.
A simple rule of thumb for determining the length: the blade should be twice the diameter of the logs that will be cut with it. The teeth of a short hacksaw will bite into the wood, requiring much more effort to work, which will quickly cause fatigue. The width of the blade usually varies in the range of 10-20 cm. A narrower blade is not allowed, as it breaks at the slightest bend, but it is inconvenient to work with an excessively wide blade.
Manufacturing material
Hacksaw blades are made of tool alloy steel with a high carbon and silicon content, grades:
- 8 HF, 9 HF, 9 XC;
- 65 G, 60 C2A;
- U7, U7A, U 8, U8A, U8G, U8GA, U9A, U 10.
The metal is hardened by acting on it with variable magnetic field when there is an electric current high frequency... As it spreads over the surface, it heats up the metal layer, which is hardened after cooling. The standard hardness is 45 HR C, although it is recommended to take products with a hardness of 55-60 HR C, when the flexibility is sufficient and the teeth have high resistance. On external examination of such a tool, you can see a darkish shade of sharpened teeth.
Tooth parameters
Precision and performance mainly depends on the size of the tooth.
The defining indicator is "TPI" - the number of teeth per inch.
Between data technical parameters there is an inverse relationship:
- Blades with large teeth allow you to work at high speed, but the cut is sloppy and rough.
- The fine-toothed blade guarantees a clean and accurate cut, but the speed is relatively slow.
When determining the size of the teeth, be guided by the material being cut. To work with chipboard, for example, a high cutting accuracy is required, so a tool with a high TPI - 7-9 is selected. For cutting logs and garden work, where the cleanliness of the cut is not so essential, TPI 3-6 is enough.
The difference between a hardened and an ordinary tooth is that the first one does not dull for a long time in domestic use. But a saw with hardened teeth cannot be re-sharpened; all that remains is to discard it after use. Ordinary teeth can be sharpened, which is done with a special file marked with an accident (for sharpening saws). It is enough to carry out several times on each tooth.
Depending on the type of teeth, there are three types of hacksaws for different types of sawing:
Some modern tools have teeth trapezoidal... This increases strength and durability, but it is not easy to sharpen such a blade, since the trapezoidal teeth are difficult to shape. Because of this, the service life is greatly reduced, and after it has expired, the blade has to be changed.
The market also offers modernized hacksaws. They are effective for cutting raw wood. Wet chips in the process of work easily come out through the gaps between the teeth, and the movement of the tool is not impeded.
Types of hand saws for wood
It is impossible to say unequivocally which better hacksaw on wood. There is different variants, for different types of work. Let's describe them.
Depending on the design and purpose of the saw, there are:
- Sweeping - for longitudinal cutting.
- Cross - for cutting across the grain.
- Circumferential - for making holes, curly sawing, rounding.
- Thorns - for cutting connecting spikes and cutting out simple geometric shapes.
You can cut the material up and down only with a bow hacksaw, by sawing blanks with complex lines. The work can be done without an assistant.
Handle type
In many ways, the ease of use of the tool is determined by the shape and material of manufacture of its handle. The handles can be wooden or plastic. The surface in the place of the grip should not allow the hand to slip. This effect is eliminated by scarring the handle, or covering it with a rubber layer. The saw can be cast or with a flip blade. In the latter case, it is easy to replace the blade.
Conventional handles are made of plastic. The prefabricated plastic handles of two halves do not have sufficient rigidity, it is much more convenient to handle the tool with a one-piece handle with a rubberized pad for fingers. The rubber insert allows for a tighter grip, which prevents the formation of calluses.
To choose the right one hand hacksaw on wood, you need to follow a number of recommendations. Pay attention to the following:
- Target... For carpentry work, you need a saw with fine teeth, which will provide high precision sawing. Carpenters need coarse teeth.
- Uniformity of the web... Gently bend the blade at an angle of 30-45 ° and release it. The slightest deviations on the fold line (even within 2 mm) indicate the low quality of the metal.
- Frequency of use... If the saw is needed for one-time work, it is better to take a tool with hardened teeth. The service life is quite long, and you don't have to worry about sharpening and wiring.
- Price... High-quality models from leading manufacturers are much more expensive than consumer goods. But the high price is a kind of guarantee of wear resistance and durability. However, for one-time work, it is impractical to buy an expensive tool.
Decide on the purpose of the tool, see how it lies in your hand. Read the attached instructions, if available. These minimal "wisdom" are many times reduce the risk of choosing the wrong tool.
