When sawing laminated chipboard jigsaw has to deal with the following problems:
- saw line irregularity
- chips on the surface of the chipboard
- end irregularity
To solve these problems, there are the following methods.
To make the cutting line smooth, it is recommended to use bimetallic files. They cut better and, therefore, the likelihood that the file will be taken to the side is reduced. It is also recommended to use a file with set teeth ( T144DF), then the cut is obtained as even as possible. The same file will provide an end that is strictly perpendicular to the surface due to its thickness.
To get a perfectly even cut, you can attach it to the part to be sawn with the help of clamps metal corner parallel to the cut line at some distance from it. For various models jigsaws, this distance can be different, for example, for a jigsaw Makita 4329 it is equal to 37 mm
The disadvantage of this saw is that it is too big size teeth, resulting in a lot of chipping. To avoid this, you can use a special anti-splinter insert and / or stick on chipboard along the cut line masking tape from the top side (or better from both). In this way, almost perfect cutting quality can be achieved. If you are professionally engaged in the manufacture of furniture, then this method will certainly not work (insufficient quality and low productivity), but for homemade furniture will fit perfectly.
You can also use a saw T318BF. It is specially designed for sawing laminated chipboard and provides a clean cut, with virtually no chips. But unlike T144DF it is not so thick and its teeth are not so far apart, as a result of which there is a high probability that the file will be taken away and the cut will turn out to be uneven.

The electric jigsaw is the most convenient and universal tool for complex work on wood. With it, you can produce artistic carving, prepare various parts for carpentry and solve other problems.
Operating procedure
To get the best result of work, you need to know how to cut with a jigsaw correctly.
- The material being processed must be securely fastened. Poor workpiece clamping is one of the main causes of sawing errors. The jigsaw can jump off, go off the markup, or even go in an arc. By the way, if the jigsaw cuts crookedly, check if the direction of the cut does not coincide with the direction of the fibers.
If so, then it is better to make a drink circular saw.
- When it becomes necessary to make a cut on the inside of the workpiece, you should pre-drill a hole at the start of work.
- When working with the tool, do not make great efforts. An electric tool cuts wood quite well and without undue pressure. If you make a serious effort to advance the jigsaw, the saw and motor get very hot, and the risk of breakage increases. Besides, overpressure - main reason chips.
- When cutting hard rock wood, it is advisable to add a little machine oil to the canvas.
- Sometimes you have to work at low speeds. In this case, it is necessary to take frequent breaks in work, as the saw gets very hot.
Problems with accuracy
Consider how to cut with a jigsaw exactly:
- The object of processing must be securely fixed. Moreover, in such a way that it was convenient to make a cut.
- In case of particular uncertainty or for a greater guarantee of accuracy, it makes sense to use guides. For straight cuts, you can use wooden block, fixed along the markup. If the shape of the cut is complex, then the situation becomes more complicated. In this case, you can use patterns, if any, or you will have to reduce the speed of work due to more accurate jigsaw guidance.
- One of the reasons why a jigsaw cuts crooked is problems with the saw. Perhaps it is dull or has chipped teeth. Noticing that the jigsaw literally turns itself where it likes, inspect the saw.
- Breakage of a jigsaw. For example, if the motor runs jerkily, the likelihood of a crooked cut increases dramatically. Likewise, other failures of the mechanism can lead to a drop in accuracy. Such problems are difficult to fix on the spot, as diagnostics are required, and possibly repairs.
- Finally, the skill of the performer greatly affects the accuracy of the work. If you are a novice carpenter, do not get upset because of periodic failures: accuracy comes with experience.
chipped
Another serious question is how to cut with an electric jigsaw without chipping? These usually form:
- with excessive pressure on the tool;
- when working on thin material near edges without reinforcing stops;
- when using unsuitable (worn out) saw blades.
Avoid these actions, and you will reduce the likelihood of chipping to a minimum. Also, some models allow the use of special anti-splinter inserts for a jigsaw.
Anyone who has ever had to cut chipboard or wood with a jigsaw knows that they almost never do without chips on the material.
You can of course use special files for a fine cut.
Smooth sawing of material with a jigsaw
For example like this. But even they do not always provide a cut without chips. And what to do?
Let's see why chips occur. Watch how the chip appears. When the finishing file goes down, the teeth come out of the material with little to no sawing or chipping. On the contrary, they saw upwards and the teeth at the exit cling to the material and break it out. Near a tree, adjacent fibers cling, while chipboard has chips along with a coating.
Now try sawing two layers of chipboard at once. You will find that the bottom layer has been sawn clean on both sides. If you think a little, it is not difficult to understand why this happened.
This happened because the top layer of chipboard did not allow chips to form.
After these small observations and experiments, you can quite easily solve the problem of sawing with a jigsaw without chips. So what should be done?
I want to draw your attention to the fact that when drilling holes, the same picture is observed: at the exit of the drill, chips are also easily formed, so you need to press some unnecessary part from the exit side of the drill when drilling through holes.

Smooth cut with an electric jigsaw. How?
Homemade device for precise cutting of boards with a manual circular saw
It is extremely difficult to make an accurate transverse cutting of the board with a hand-held circular saw in the standard version. To get the perfect cut in accordance with the markings, a simple makeshift fixture, easily made from scraps in your home workshop.
The cutter is designed to cut boards from 100mm to 250mm wide in 50mm increments, but can be easily resized to suit your needs.
How a Hand Saw Attachment Works
The device in question is extremely simple and consists of only a few parts: the base for the saw, the guide rail, the stop bar and eccentric clamp providing a secure fixation even on sawn timber, spread with small deviations in width.
Scheme of a device for a hand-held circular saw.
It is very easy to use homemade. First, markings are made on the board.
Then a homemade fixture is installed on top, the lower stop of which is pressed against the edge of the workpiece, and the right edge is aligned with the mark.
Photo fixture for a circular saw.
Photo fixture - bottom view.
Now it remains to put the circular saw on the base and make a cut, pressing the edge of the sole against the guide side stop.
Cross cutting of the board using the manufactured fixture.
The result will be a perfectly even cut that exactly repeats the markup.
With this attachment, it is convenient to make many cross cuts when frequent movement of the tool to a new cut line is required, for example, when grooving in bars. It will also come in handy if it is necessary to reduce the length of the workpiece by a few millimeters, and it will cope with this task no worse than a miter saw.
How to make a device with your own hands
The cutting attachment is made for a specific model of power tool. Measure on your circular saw the distance from the engine to the bottom of the sole and subtract 5 mm. The result obtained is the height of the guide stop.
Withdrawal the right sizes circular saw.
Prepare according to the dimensions of the plywood base with right angles and wooden slats with parallel edges.
Blanks for assembling a device for a cross cut with a circular saw.
Measure the distance from the cutting disc to the edge of the sole.
Add an allowance of 6–10 mm and install a guide rail at this distance from the right end of the plywood. Fix the bar with countersunk screws, controlling its strictly perpendicular position.
Screw the stop bar on the back side and fix the fixture on the workbench.
Cut the plywood with a circular saw to the final width, creating a reference end for precise positioning of the fixture along the markup.
Draw a cam cam template on paper.
Eccentric clamp drawing.
Mark the piece on 10mm plywood and mark the center of the bolt hole with an awl.
Cut the workpiece with an electric jigsaw.
Make a washer with a diameter of 50 mm from the same plywood using a sliding drill for a ballerina wood.
Grind the blanks and pick up an M6 or M8 furniture bolt with a mustache (or with a square headrest), a handwheel nut, a washer and a bushing. The latter can be made from a tube of suitable diameter. The sleeve length is the total thickness of the base, arm and plywood washer.
Ready plywood eccentric.
Make holes in the base with a drill according to the diameter of the sleeve, which serve to rearrange the eccentric clamp according to the width of the board to be cut.
Hole drilling pattern.
Assemble the eccentric mechanism: insert a bolt with a sleeve from above, and put a wooden washer, the cam itself and a steel washer from below. Tighten the parts with a nut.
Stick with inside stop strip sandpaper to prevent slippage when the eccentric locks, which can occur if the fixture is fixed on a smoothly planed workpiece.
The clamping system of this device has a stroke that ensures fastening on the boards with a run-up in width of about 10 mm. If you need to cut or trim other sizes of workpieces, simply place a piece of wood in front of the stop bar.
An example of using a crosscut saw with a hand-held circular saw on a smaller board.
If desired, the potential of the considered device can be expanded by adding a cutting angle of 45 °. To do this, you will need to slightly increase the dimensions of the support platform and install a second thrust bar at this angle.

How to cut straight with a jigsaw? This tool is a saw with an electric drive. He can saw various materials:
- wood;
- metal;
- plastic;
- tiles.
Working with a jigsaw is simple if you follow the rules: the table must be stable, the material is firmly fixed, the correct saw is selected.
The tool can cut parts, cut workpieces in a straight or circular line. How to cut with an electric jigsaw?
Principle of operation
Materials and tools:
- wood;
- jigsaw;
- protective glasses;
- protective gloves;
- machine oil.
First of all, it is necessary to firmly fix the material being cut.
If the jigsaw cuts crookedly, you need to check the stability of the desktop and the strength of the workpiece. Using a jigsaw, it is undesirable to cut a tree along the fibers, since it will be quite difficult to make an even cut.
If, nevertheless, it is necessary to perform just such a work, then it is necessary to apply parallel stop. It is attached to the jigsaw with one side, and the other side should rest against the edge of the wood. This will ensure an even cut.

The Right Process
If during work it becomes necessary to cut a circle inside the wood, then you need to drill a small hole in the center of the future circle. Then they put a jigsaw in it and move towards the circle indicated on the material.
In the event that it is necessary to cut a hole in the shape of a rectangle, you need to move the saw along the side of the rectangle, then smoothly around the corner, cut out the next side. When required hole will be ready, you need to draw the corners.
When performing work, do not press hard on the tool, as this can cause the device to overheat and fail. Don't use the saw for too long as it gets dull and starts to catch on the edges of the wood.
When sawing durable materials, you need to lubricate the file with machine oil. This will make cutting easier.
If the work is performed at low speed, then you need to take breaks, as this will cause the device to overheat.
When working, you must follow safety precautions, cut with goggles and gloves.
After finishing work, the jigsaw must be cleaned and lubricated with machine oil.
The device can have a normal and pendulum stroke. In the first case, the jigsaw moves vertically. At the same time, it cuts the wood when moving up. A device that uses a pendulum stroke, when moving up, additionally feeds a jigsaw forward. With this method, the speed of work increases, and the tool blade wears out less.

Sawing technique
In progress construction works sometimes it becomes necessary to cut the material evenly, with extreme precision.
Materials and tools:
- wood;
- jigsaw;
- guides;
- clamps;
- pencil;
- roulette.
For a smooth cut with greater accuracy, you need to use a tool with a high frequency of blade movements.
The file should be wide, designed to work with wood.
Work will be done with a guide. To do this, you can use a flat board or rail.
It is necessary to prepare 2 clamps. They should fit the workpiece and guide.
The workpiece must be placed on an elevation so that the jigsaw does not rest when cutting.
Then you need to measure on both sides with a tape measure the required width of the section to be sawn off. Make marks. Then they are connected along the ruler, getting a cut line.
Then the guide is laid at the required distance from the cut line and fixed with clamps. After that, the jigsaw is placed with a file to the cutting line. Then press the guide against it and fix it with a clamp. You need to fix it so that it does not move, but not too much.
Then the same actions are performed on the other side. Here it is necessary to clamp firmly, but so that the wood does not get depressions.
After that, they move on to the first clamp. Check its installation and clamp it.
Produced necessary measures for an even cut.
Now turn on the jigsaw. Install top speed. The pendulum stroke regulator is set to the number 1. Install the tool with a file to the cut line. Press the side of his platform to the guide and start cutting.
When working, do not press too hard on the device. Slightly move the tool forward while controlling its platform. It should be pressed against the guide so that it does not move. When a few centimeters remain until the end of the cut, you need to hold the sawn off part so that it does not break off.
This is where the work ends. The cutting line is perfectly straight.
How to cut straight with a jigsaw? This question interests many, especially at the moment when a person is engaged in construction. This tool helps to cope with a difficult task. But what is it? According to external data and the main purpose, it is comparable to a saw that has an electric drive. In this case, you can cut various materials:
- Wood products.
- Metal constructions.
- Plastic.
- Tiles.
And to make the work of any purpose is not so difficult. According to the masters, the main thing is to create all the conditions to make it convenient to work. How to cut straight with a jigsaw? The first is to use only a flat and stable surface. The material to be cut must be firmly fixed, and a saw of the required sharpness and size must be selected.
Such a saw is considered unique because it can work on almost all materials. In addition, she does not only straight lines. It can be used to create curved cuts. But before you start the process, you should understand which jigsaws cut evenly and with high quality.
Work system
To fully understand the process, you need to prepare everything first. Here's what you need if the work will be done on wood:
- Any piece of wood.
- Jigsaw with electric drive.
- Personal protective equipment - goggles, gloves.
- Machine oil.
Requirements
The very first thing is to securely and firmly fix the material on which the work will be carried out. It also happens that an error occurs, and the jigsaw starts to cut unevenly. It is worth finding out the reason, otherwise it will not be possible to achieve the desired cut. This is the stability of the table, as well as the reliability of fixing the material. It is not so difficult to make even cuts with such a tool, but if you choose the direction along the fibers, nothing will work. Although people with experience can even cope with such a task.
How to cut straight with a jigsaw? If such a need is required for a person without experience, then the following steps must be performed - this is a parallel emphasis. To do this, on the one hand, fastening to the jigsaw is carried out, and the second side - an emphasis on the edge of the tree. This is how it will turn out to make the cut even and without residue of fibers.
Everyone can recognize the device of this unit in the instructions. When buying, many recommendations are given by managers. Each manufacturer invests instructions, this is no less useful information and is worth studying. Everything should happen in stages, if questions arise, then they need to be resolved, and not continue to work “at random”.
Making holes
How to cut a hole evenly with a jigsaw, for example? Often these steps are required. In order to install the jigsaw in the center of the future hole, a small hole is made, after which the cutting unit is inserted there. Then they simply pass along the marked line of the circle. A rectangular shape is also performed (namely, you need to move the saw along the side of the rectangle). But the corners smoothly bend around. Next you need to cut out the next side.
One more important point in work - do not press hard on the jigsaw. This condition is often violated by beginners, which leads to overheating and then to a breakdown. In addition, one saw should not be constantly used, otherwise it will become dull and will cling to the material being cut.
Durable materials not easy to cut. To make the procedure quick, machine oil is used. They are lubricated in the process, and the work goes quickly. Low speed is another problem with such tools. The problem is that it overheats again. No one ruled out safety precautions, and even at home, do not forget about glasses and gloves.
When all procedures are completed, it is worth wiping the equipment and lubricating with engine oil. On sale there is an installation with a conventional and pendulum stroke. The first option is different in that the movement occurs upwards on any material. In the presence of a pendulum stroke and upward movement, an additional knife is thrown forward. This allows you to increase the process of work and at the same time do not wear out the saw much.
Features of the operation
How to cut straight with a jigsaw? Before starting work, you should find out the whole process, otherwise you will not be able to achieve the desired result. Often, when working with any materials, it is required to create a cut with maximum accuracy. It is the jigsaw with electric drive handle this job.
Here's what you need for this:
- Material for work.
- Jigsaw.
- Guiding tools.
- Clamps.
- Pencil.
- Construction roll.
Getting Started
The movement of the cutting blade must occur precisely so that the cut is the desired one. It is good when the frequency of movement is high. For this, a saw of the maximum width is taken (this is suitable for wood). The main thing in this process is the use of a guide. A flat board or rail becomes the main assistant.
Clamps are indispensable. They have a workpiece and a guide. The material to be cut should be placed on a slight elevation. This helps not to rest against the jigsaw. After that, the distance that should be cut off is fixed. For this, a roulette wheel is used. After applying the risks with a pencil. Then, using any ruler, these marks are connected, and a cut line is obtained.
What to do next?
Next, you need to fix the guide in a certain place. Clamps help with this. Fixation is performed from the cutting line. After that you need electrical appliance position the saw against the cutting line. Now they press the guide and also fix it, there should be no movement, but you should not press it too hard either.
Then they move to the second side and also fix it. The level of fastening is the maximum, but do not forget that some materials can be pressed through. When the whole process is completed, you need to move on to the first clamp. Do its installation correctly and clamp. Only then can you begin to perform an even cut. Otherwise it will not work quality work.
Now you can turn on the jigsaw and begin the process itself. The speed is high, the pendulum stroke should be at one. And the tool itself is placed so that the file is on the cut line. Only after this, the work will be done with high quality, and the line itself will turn out to be smooth and impeccable.
Do not forget a single moment - if a person has no experience, then any mistake becomes fatal. Especially when you need to cut parts, the number of which is limited. Experts recommend learning how to perform all actions on any unnecessary material and only after that proceed to the main work.
What else do you need to know?
Any device has accessories. They allow the whole process to be made more precise and to simplify something. It is believed that sawing plywood with a jigsaw is the easiest process, since the material does not have thick. Sometimes you need to cut small parts. How to cut plywood with a jigsaw? This will be simplified by having a special table. It mostly comes with this electric tool, although many build it after purchasing it themselves.
The use of a clamp is always necessary. The same applies to the table - it is fixed using such an installation. But the process of cutting occurs in the opposite direction. But the movement is produced not by electrical equipment, but by a detail. Experts believe that this way the lines are accurate and correct.
Many beginners may encounter such a problem as clamping the saw. But how to deal with it? Often, many use a replaceable plate. This applies to additional tools. At the same time, the most diverse material is taken to create such a component. And its fixation occurs to the sole of the electrical installation. And already with the use of components such as a guide bar and an adapter, an accurate line is obtained.
Sometimes when sawing, the material starts to heat up, and the process will simply slow down. In such a situation, it will be necessary to cool the material. For this, a simple cold water. It is fixed on the support sole. Often people have a question about how to cut a laminate with a jigsaw evenly. Everyone knows that it is a tree, for this reason the same principle applies to it. In the process of laying a laminate board, it is such a tool that helps to make the process easier.
It is better to cut from the back side, and the smallest saw is taken for this. This helps to avoid deformation along the cut line. Since metal parts heating occurs. Here you need a cold liquid, and for a tool - machine oil. To create a cutting line of any shape, the thinnest saw is taken. Another addition is the circle cutter. Before installing it, a hole is made in the center.
Curved saw cut
When creating a curved cut, a problem arises - the material begins to move. Therefore, before starting work, the table is well fixed (and the part itself too).
How to cut chipboard with a jigsaw exactly?
This question interests everyone. It is important to carefully go around the corners, but you can make a circle in the part only after all other cuts are completed. For such work, the main saw is used. She is enough. Do not use force on the tool. The work of such a tool should take place in several stages:
- When working with hard materials - the use of engine oil and coolant.
- When working at high speeds, you need to take a rest, otherwise the equipment will overheat and fail.
- Compliance with safety regulations, the use of gloves and glasses.
- At the end of the work, the device is wiped and lubricated with oil.
There are also manual units. How to cut correctly and evenly manual jigsaw? It's easier because you can stop and make corrections, although many people think the opposite is true. In any case, the jigsaw is considered indispensable equipment for home. Because it works on any surface and creates straight cuts. If possible, then you need to buy it. He will definitely not be superfluous in the economy.
