With a saw, the tool should be set to the cutting line. The guide is squeezed with the platform side. After that, they start cutting.
The tool moves forward smoothly and the platform is carefully controlled. The platform and the rail must move towards each other so that nothing moves. The sawn off part must be carefully held with a few centimeters left to the end. Then the part will not break off.
What to do if you have problems with accuracy
- The main requirement is the reliable fixing of the material for which processing is required. In addition, the cutting should be convenient for the person himself.
- It is better to use guides if there is a lot of doubt that the person will cope with the work. For example, wooden block will be an excellent guide when cutting straight. It is simply fixed along the markings. It is much more difficult when the shape of the future product is quite complex. Then the use of patterns is recommended. Otherwise, the speed of work will have to be reduced to make the result more accurate.
- Saw problems are one of the most common problems when sawing. There is a possibility of chips, dullness. It is better to inspect if it is noticeable that the instrument is strongly retracted to the side.
- If there are jerks, there is a possibility that the cut will go to the side. Other failures in the instrument also lead to a drop in accuracy. It is recommended to start fixing such problems immediately, on the spot.
- The skill of the performer himself also affects the accuracy of the final work.
Professional secrets
It is imperative to check how firmly the canvas is fixed.
This mechanism can have its own characteristics, depending on the manufacturer.
For working with any cutting tools, the fastening of the blade, its general position, is really important.
A useful device will be responsible for the removal of sawdust. Its working principle is very simple. There is a flow of air from the fan cooling the motor.
It is used to remove debris. The retract system makes the cut line more visible to the eye of the master.
The drill can be easily changed when making holes using a technique called "pocket". To do this, it is enough to tilt the jigsaw forward, then the tips with a rounded shape will rest on the surface being cut.
Above the line of the future cut, the blade must be positioned with maximum accuracy. Lower the control saw horizontally and then continue practicing.
For such work, first marks are made inside the material, and then, already along them, the instrument itself is found. With a square or rectangular shape, the canvas is pulled back a little before the wizard guides the tool to the next side. And so all four are processed.
The use of plunge sawing is permissible if it is impossible to create holes of the required dimensions. For this, the jigsaw tilts forward until the file reaches the workpiece. Gradually, a through hole appears during this process.
What else you need to know about working with a jigsaw
At its core, this device is regular saw, only equipped with an electric motor. It is recommended to take for carpentry work when it is necessary to cut surfaces with wide, even sides.
In this case, the tool itself remains in place. The movement is organized only by the material that needs processing.
The cut is performed from the back side, then its characteristics will please.
- Machine oil for lubrication is needed if work is carried out with metal, tiles.
- Cold water should cool the cut line when processing metal.
- Personal protection cannot be provided without glasses and gloves.
- With an electric jigsaw, plastic is processed only from the rear, otherwise it is impossible to get an even cut.
A special plate is attached to the support sole of the jigsaw, it allows for greater accuracy. This makes the movement of the saw blades smoother over the surface. Any will be cut exactly.
About the varieties of the instrument
First of all, they are professional or household. Professional means the fixture will have a lot of power. It is usually 580-720 watts. But for household appliances it is less, only 320 watts. But this is quite enough for a small amount of work at home.
The higher the power of the tool, the thicker material it handles without problems.
Any type of tool can handle holes up to 15 mm. But we must take into account that jigsaws, in which 1000 rpm is equal to the lowest speed, will not cope even with plastic.
Jigsaws are sometimes divided into groups depending on how the saw is attached to them. For example, for a bore shank, smooth or cruciform. The latter two have become the most common since they are best suited to household tools.
Design and its features
Each jigsaw has a so-called support sole. It always rests on the part that needs to be cut. Thanks to this, the accuracy of the work is significantly increased.
The sole can be easily rotated to make bevel cuts. Some manufacturers produce in which the main tool is fixed only at a certain angle.
The file acts as the main cutting tool. Breeding of teeth, method of sharpening, size, shape, materials - they are literally different for each model. 75, 85 and 100 millimeters are the most suitable lengths if you need to cut low density materials. Saw step size is also becoming a fairly important parameter.
- Metal requires a pitch of 12 millimeters.
- Have wooden products he is from 2.5 to 4.
About accessories
No special effort is required to obtain maximum results. The tool can work as a stand-alone fixture without any additions. But there are parts that can increase the working capacity of a conventional jigsaw.

Laying laminate flooring is no more difficult than folding a puzzle. The most tricky part work - cutting lamellas. Consider how to cut the laminate so that the cut is even, and defects in the form of chips or cracks do not form on the lamellas.
Since laminated boards are made from pressed wood, the trimming must be done with a sharp tool. Otherwise, chips and cracks will form during the trimming process, the trimmed edge will be uneven.
You should also pay attention to the fact that it is impossible to lay the laminate close to the walls. This is flooring depending on the change in the level of humidity in the room, it may slightly expand and contract. The lamellae laid back to back will deform during expansion, and they will have to be replaced with new ones. The gap between the wall and the laminated board must be at least 1 cm.
Tool used to cut laminate flooring
You can trim the laminated board with the following tools:
- electric jigsaw;
- grinder;
- a hacksaw for metal;
- with a special tool designed for cutting laminated boards.
Before describing the cutting mechanism, I would like to draw your attention to preparatory work to do. First of all, you need to measure what size the slats should have adjacent to the walls. At this stage, you need to take your time.
Using a simple pencil on the back of the lamella, it is necessary to mark the cutting point. Then, you need to draw a line along which the lamella should be cut. You can also make a designation on front side slats. But in this case, it is advisable to stick masking tape on the surface of the lamella. And already on it to make notes.
Another nuance that needs to be taken into account is the cutting width of the tool used.
So, if the markup is done, then you can start trimming the laminate.
Using an electric jigsaw
If you need to get the job done quickly, then you can't do without an electric jigsaw. It would be nice to have experience with this tool. If there is none, then it is advisable to practice on an unnecessary piece of wood or an extra lamella.
To prevent chips from forming on the laminate during pruning with an electric jigsaw, it is necessary to choose the right saw for wood. It must be sharp and have fine teeth... The tool must work at high speeds. In order for the cut to be even, it is necessary that the cutting part of the electric jigsaw moves smoothly along the lamella.
Before starting work, you need to fix the lamella. Cropping will be done according to the markup. Therefore, the side on which the markings are made should be directed upwards. Most often, the markings are done on the back of the laminate. The laminate plank is placed on a hard surface. It is advisable in this case to use a stool.
Using the grinder
In fact, the tool that we used to call the grinder has a completely different name. This is an angle grinder. It is ideal for trimming laminate flooring. During work, you can use both those discs that are designed for working with wood, and those that are designed for working with metal.
It should be noted that the teeth of discs designed for working with metal are thinner and smaller. Therefore, when trimming the laminate, it is advisable to use discs for metal. There is also a special disc on sale that is designed for cutting laminated boards. Working with such a tool, you can avoid the appearance of chips on the trimmed bar.
You need to work in the same way as when using an electric jigsaw. All movements should be smooth, and the trimmed bar should be fixed on a solid surface. During operation, a specific smell appears. This is due to the fact that the wood is in contact with the hot disc of the grinder.
Using a hacksaw
If you don't have a grinder or electric jigsaw at hand, you can cut the laminate with a hacksaw. You can use not only the tool that is designed for working with wood. A hacksaw will also work. It should be noted that the trimming process will take a lot of time.
Before starting work, you need to carefully inspect the tool. If the teeth of the hacksaw are large, then chips cannot be avoided. It is also worth considering that the cutting part of the hacksaw for wood is quite rough. Therefore, it is better to use a hacksaw for metal. It is advisable to rub the cutting part of the hacksaw with paraffin.
Before starting work, as in previous cases, it is necessary to fix the laminate plank on a hard surface. Experts do not recommend pressing on a hacksaw. The cut will be uneven.
Using a special tool
To cut a laminated board, in addition to a jigsaw, a grinder and a hacksaw, you can use a special tool, or rather a machine. At first glance, the equipment can be said to be very similar to the guillotine used to cut paper. The machine consists of a support on which a lamella, blades and handles are located. After pressing the handle, the blade is lowered onto the lamella. The cut is smooth and beautiful.
The machine works silently, leaving no debris and dust behind. No defects are formed on the material during trimming.
You can, of course, purchase such a machine. But, if you are not professionally engaged in repairs, then almost all the time it will simply gather dust in the corner.
The laminate cutter is used exclusively for cross-cutting the lamella. If you need to cut the laminate strip lengthwise, then you cannot do without a grinder, jigsaw or hacksaw.
The cut is not always perfect. However, it should be remembered that the skirting board will be laid on top of the laminated board. It will cover the uneven cut. If, however, a crack has formed during the trimming of the lamella, then do not worry. A similar defect can be corrected with a special paste.
We figured out how to cut the laminate. But, finally, I would like to note that when using an electric jigsaw, grinder or hacksaw, construction debris in the form of sawdust will be generated during operation. Therefore, it is advisable to pre-cover the floor with paper, film or cloth. It is even better to work not in the room in which the installation is carried out, but in the next one. After all, the decorative flooring should be laid on a clean surface.
After cutting the laminate plank, wipe the cutting area with a damp cloth. This is done in order to get rid of the dust that has formed during the cutting process.
Today we will tell you what affects the quality of sawing, how to cut the chipboard smoothly and cleanly, and also how you can cut with a rail and without a guide with a conventional circular saw.
We will show using the example of a hand-held circular saw, but this does not affect the cutting techniques in any way, the difference is only in insignificant details. You can get a similar quality of cut on a cheaper tool if you follow our advice.
What affects the quality of the chipboard cut?
In this case, we will cut chipboard, this is the most capricious material for sawing, because it has longitudinal and transverse layers, a rather delicate and thin veneer. But on the other hand, it has a tough adhesive base, which will also interfere with us.
Saw blade. How to choose it?
When cutting chipboard, the saw blade must simultaneously cut cleanly and be resistant, because the glue in its properties is very close to glass and quickly blunts the tool itself. Therefore, in the process of cutting chipboard, you need to choose sufficiently good discs to cut them without losing quality for a long time.
What is the difficulty of sawing with a circular saw with discs?
If we look at the cut of the workpiece, we will see that it is full of seizures, because it is practically impossible to keep the saw straight in the cut by hand.
On the saw blade there is a difference in height between the body of the saw itself and the sawing part - the tooth. Due to this distance, the disc is able to guide its position in the cut. Accordingly, as soon as it changes its geometry, the rear teeth begin to press on the chipboard workpiece and leave traces on it.
It is important to have the workpiece face down. Why?
The disc rotates from the bottom up, it cuts the pile of the workpiece up to the base. Thus, below, on the front side, we always have a clean surface. Problems begin to form at the top, where the teeth come out of the workpiece. This is how explosions, chips, pile are obtained.
How can they be minimized, or avoided altogether? There are several simple tricks and we will tell you about them now.
Reception 1. Cut along the guide
We install a guide (tire) on the workpiece, set the cutting depth and perform the cut. As you can see for yourself, even on outside of our chipboard blanks, there are no chips, no explosions. The cut itself is even without signs of scoring or side waves. Why such difference?
What is the merit of the guide?
When we saw with a disc, we inevitably wiggle the saw, the so-called "iron movement" is obtained. That is, when we move our hand, we all the time move the saw to the right, to the left. The guide, which has a rigid edging, avoids this.
Accordingly, when we drive the saw along the guide, it does not move itself saw blade works smoothly without changing its position. It turns out a perfect line parallel to the guide.
What if there is no hand-held circular saw and guide?
You need to make the guide yourself. We find an ordinary profile, you can take a rule, any even rail, the main thing is that its geometry is even.
We measure the distance from the saw blade to the edge of your chipboard workpiece. We attach the guide to the workpiece with any clamp and start cutting.
The main thing in the process is to constantly press the saw against the guide. That is, your hand should always guide the saw towards the homemade tire.
After cutting, you will get an almost perfect cut, the cutting line is barely visible. We made a very high quality cut, the cut itself is clean, no side marks are visible on it. Except for a small pile on the back of the workpiece.
Where did this pile come from, because we worked with a guide (tire)?
There is a special plastic protective tape on the purchased cutting bar. This tape prevents the pile from rising and the saw cuts it. In this case, we did not have this tape, so we got this pile on the surface.
What to do with the pile in this case?
There are two options:
1. Take ordinary masking tape. It is glued to the place where it was cut, marking is made on it and sawn together with masking tape... The scotch tape keeps the growth in place and when we cut it, we get everything clean.
2. Just drive the saw blade more slowly. That is, if you do the same with a slower feed, then there will be much less chips.
Reception 2. "Reverse cut".
The first pass is performed in an unusual manner - in reverse. That is, the circular saw rotates in the direction of feeding the workpiece. We set the minimum cutting depth, turn on the saw and move not forward, but backward.
If you have a regular saw, then simply fix the saw with a minimum overhang. The point of the first pass is that the blade, moving along the guide, only clings to our workpiece. We need a small groove in the chipboard.
Having made the first - undercutting cut, you will make sure that there are no chips at such a feed (backward). The surface is perfect!
Now we will set the saw to full depth and cut the workpiece along this groove with a regular cut - forward feed. We will have two cuts per piece. No gouging waves, arson, nothing - perfect quality!

Without any exaggeration, a tool such as a jigsaw is irreplaceable assistant in every house. With this tool, you can easily cut out a wide variety of shapes from a wide variety of materials. It is the jigsaw that is one of the most convenient tools for cutting circles, ovals and other complex shapes.
So how to cut with a jigsaw correctly and evenly? It is necessary to follow the instructions, and for this you will also need:
- protective glasses;
- machine oil;
- gloves;
- jigsaw.
In order to cut smoothly with a jigsaw, you must act as follows:
- Before starting work, it is necessary to strengthen the material with maximum strength. Cutting along the grain is strongly discouraged as it is very difficult to achieve evenness in this case. In this regard, it is best to use a circular saw; in the absence of such a tool, you can use a parallel stop. Such rip fence it is necessary to attach one end to the jigsaw, and the other end should rest against the edge of the workpiece. In this way, the most even cut is made.
- If it is necessary to make a cut inside the workpiece, then first a hole is made in the circumference. Then insert a jigsaw into the hole made and start moving in the direction of the marking. After the desired hole has been cut, the corners of the workpiece are easily corrected on both sides.
- In order to cut correctly with the jigsaw, do not use force when pressing the tool. Otherwise, the blade will quickly heat up, which can lead to breakage. You shouldn't use one file. long time, since it becomes dull pretty quickly. And such a file makes scuffs at the edges of the material, which significantly impairs the quality of work. If it comes cutting materials of increased hardness, the blade must not be lubricated big amount machine oil. Thus, it will be easier to work with a file, in addition, the service life of the file will significantly extend.
- When working with a jigsaw at low speeds, the jigsaw needs a break, since in this process, engine overheating often occurs. In this case, it is necessary to strictly observe safety precautions, the presence of protective glasses and gloves is simply necessary. After the work is completed, the tool must be cleaned and lubricated.

Process features
An electric jigsaw is available with a pendulum and normal motion. When the stroke is normal, then the blade must be moved vertically, while the material is cut when moving up. The working speed is quite high, the blade wears out much less.
As for working with a jigsaw with a pendulum stroke, the principle of operation is the same, but it must be borne in mind that it is best to work with soft wood and plastic, but it is better to refuse cutting steel sheets with such a tool.
If you need to cut a hole round shape, then an initial hole is drilled in the workpiece, then a file must be inserted there.
Then you should cut along the mark. If you want to make a hole in the form of a square or rectangle, then cut it in a straight line. Then the cut out area is removed and the remaining parts, which are in the shape of a triangle, are cut out.
If it is not possible to make a starting hole in the workpiece, plunge sawing is advisable. Wherein electric jigsaw leans forward until the file reaches the workpiece. Thus, the file makes a through-type hole in the workpiece. Using a jigsaw, you can cut bevels.
When working with a jigsaw, it is necessary that the table is stable, the material is securely fixed and the correct saw is selected.
Sawing with a jigsaw so that everything is smooth is not at all difficult. A guide is attached to the tool, which is then wound over the edge of the workpiece.
If everything is done exactly like this, then the movements of the file are carried out smoothly and without special efforts... In the event that the edge is curved, it is necessary to cut out according to the markings, which should be done before that.
If you want to cut a sheet of wood that is thinner, chips may appear. In order to prevent this phenomenon, the workpiece must be placed face down.
For carpenters, boards and beams are the most common blanks, of which crafts and wood products are subsequently produced. And the first thing that the material undergoes is sawing into pieces of the required length. At the same time, you should know how to cut the board evenly, because incorrect performance of this operation can spoil the workpiece or significantly affect appearance, and not for the better.
At large enterprises, the problem of how to exactly cut a bar or board does not arise. Any serious production has high-precision equipment that performs this type of work. At home, you have to make do with what is at hand. At the same time, you still need to be able to use the tool or equipment correctly in order to saw off the board correctly, and the cut turned out to be flawless.
Note that many companies that sell boards and beams provide cutting services. And for this they use all the same specialized equipment, so the purchased material will be cut efficiently. But it is not always possible to use such a service, and it often happens that you only need to cut one workpiece.
Cutting the board at home
You can cut a board at home with tools and equipment such as:
- a circular saw;
- hand saw;
- angle grinder ("grinder").
Each of these options has its own specifics, which is important to consider before starting work, that is, you need to know how to cut a bar or board with this or that tool so that the cut quality is acceptable.
Circular saw - high productivity and ease of use
The circular saw is the best option to perform work. It has excellent performance and allows relatively short time cut a considerable number of blanks, and with high quality... In addition, such a saw allows you to cut the material longitudinally, but you need to know how to cut the board straight along.
One of critical criteria when choosing a circular, is the maximum cutting depth. There are devices on the market that cut materials with a thickness of 30 to 130 mm. That is, you can choose a machine both for cutting only thin boards, and for sawing bars.
It is also worth paying attention to itself cutting tool... Discs with a large number of teeth will provide a neat, high-quality cut, while the cutting speed will be low. But discs with a small number of teeth will provide high productivity of work, but the cut quality will also be worse.
Now about how to cut straight with a circular saw. One of the conditions quality execution work is a reliable fixation of the workpiece. If the material is weakly fixed, then when cutting the board may "go", and the cut will be uneven.
If the circular saw is hand-held, then all work should be performed on a workbench equipped with stops and guides for the workpieces. Such a device can be made independently, taking any table as a basis.
It is important to set the cutting depth correctly before starting to cut. In some hand saws there is an adjustable side guide with which you can perform longitudinal sawing material. If there is no such device, then use the same workbench.
More convenient in terms of work is the table circular, which is already equipped with everything you need - guides, clamps. Often, such equipment also allows you to cut workpieces at an angle.
During the sawing process, it is important not to exceed the force on the tool, otherwise the quality of the cut will be low, the increased load on the saw will lead to a rapid dullness of the cutting blade.
Do not forget about safety precautions when using such equipment. Work should be carried out only after checking the saw's serviceability and the correct fastening of the workpiece. Also not worth neglecting protective equipment- masks, glasses.
Hacksaw - simplicity and safety
A hacksaw is a simple tool that is quite suitable for work. And although the cutting speed is low, and considerable physical effort is required, but for home conditions such a saw is the most acceptable option.
It is not difficult to cut correctly with a hacksaw on wood. The main condition for a high-quality cut of the material is to make the correct cut. To simplify the task, you can use a regular flat bar, which is used as a guide.
Often the question arises of how to smoothly saw off a board with a hacksaw at an angle. For this, a special joinery- miter box. Moreover, it will help not only to make a cut at the right angle, but also allow any beginner to cut the board exactly.
You can also cut off a bar with a hacksaw. The only problem when working with such a blank is that you have to make a lot of effort.
The last option is to use an angle grinder with an installed wheel with teeth for work. But since the "grinder" is not intended for cutting wood, this method can be used only as a last resort: attempts to cut the board can result in serious consequences. It's better to use a hacksaw - it's time consuming, but safe.
