How to saw with a jigsaw straight
An electric jigsaw is a tool that can be used to make curved and straight cuts in all kinds of materials, trim interior doors, boards, and so on. Before you get to work, you need to figure out how to saw evenly with a jigsaw.
The tool is sawed with little effort. Simply press it against the surface of the material to be machined and set the direction. That way the cut is smoother. Excellent results can be seen with slow cutting. When sawing, make sure that the saw blade is sharp.
Another important prerequisite is that the cutting surface must not be allowed to overheat. Otherwise the teeth of the saw blade will quickly wear out. Each type of material is sawn with a certain type of saw. The functionality of a jigsaw depends on how powerful it is.
How to saw straight with a jigsaw? In order to get the smoothest possible cutting line is used:
Cutting with a plastic sole plate
One of the reasons for sawing with a jigsaw with chipping is its sole. It does not press the edge of the kerf, thus allowing it to break during the reciprocal movement of the file. This is solved with a simple plastic escutcheon.
The sole plate is cut from a sheet of plastic. It is necessary to make a kerf under the file. It is simply clamped to the board and sawn with it. The sawed-in overlay should be glued to the saw-board with double-sided adhesive tape.
After that, the electric jigsaw makes the cut even cleaner than when using painter’s tape.
Rules for a clean saw-cut
Thus, in order to correctly and evenly make the cut, it is necessary to adhere to the following rules:
- Carefully choose a saw that is suitable for your source material.
- Prepare all the auxiliary items you will need.
- Clamp the workpiece carefully.
- Pay attention to the correct position of the workpiece so you do not have to correct mistakes. in some cases the blade is placed face down.
- Practice the technique of operating the device with the help of professionals or by means of a training video.
- Follow the safety instructions carefully.
In fact, the processing of products with a jigsaw is not such a difficult task that any beginner carpenter can do. Even if a neat and even cut is not straightforward, do not despair: assess soberly what peculiarities you may not have paid attention to. And do not ignore the advice of professionals, which can accelerate the process of mastering the art of how to saw with an electric jigsaw, and reveal some secrets. Try and improve!
Ways to work with a jigsaw without chipping on different materials
This tool is suitable for working with different materials:
To understand how to saw with a jigsaw without chipping, it is worth listening to the advice of professionals. For each type of material the tool must be adjusted, a specific frequency, pressure force, smoothness of movement must be chosen.
Cutting of chipboard panels and other materials
Panels should be cut with a sharp fine-toothed saw at maximum rpm. Place the material on a flat surface. This is a must, because if there is no good adhesion between the plate and the surface, the plate will vibrate while the tool is working, and you will not be able to cut evenly. At the same time it should be pressed. Move the jigsaw smoothly, without jerks, exactly along the planned line. If these conditions are met, there will be no burrs on the chipboard and the edges will remain clean.
How to cut ceramic, porcelain stoneware
It is possible to cut these materials with an electric jigsaw, but only with special jigsaws and nozzles. They are much more convenient to work with. Porcelain stoneware and ceramics are easy to split, and the smallest splinters are produced. Wear safety glasses and gloves when sawing. Ceramic tiles are scratchable, so a plastic cover must be placed on the electric jigsaw soleplate before working. Experts advise to hold the tile in water before sawing, it will become more pliable and there will be less dust in the process of cutting. The material must be securely fastened. Clamps with rubber pads are used for this.
All sorts of ceramic tiles are sawn without pendulum motion. Straight cuts can be made by setting the switch to the smallest position.
When performing a closed cut, the tile must be drilled with a ceramic drill, with a diameter slightly larger than the width of the saw used for the cut.
How to cut plexiglass, plastic
If you need to saw plexiglass, then do it at low speed, because too rapid movement of the saw blade, it melts and smokes. Edges are jagged and hard to finish. In the process of work, a lot of small chips fly away from the plexiglass, so it is necessary to work with glasses. If you want to use the tool at high RPM so the material does not melt, you must constantly cool the tool and the jigsaw. Cool down with plain water. Feed it through a tube to the place of cutting. To avoid overheating it is advised to arrange a break in the work.
A fine-toothed saw blade is used for cutting plastic. Adjust tool depending on type of plastic. If the jigsaw is crooked, how to fix it? Saw with the pendulum swing turned off. Only then the cut will be straight and clean.

How to cut metal
The jigsaw is used to cut different metals:
With a medium power jigsaw, you can cut sheets up to 0.5 mm thick. For cutting metal workpieces up to 10 mm thick you need a professional model of the tool.
Metal workpieces are cut using saws on metal with fine teeth and pitch 0.1-0.2 mm. Set the stroke frequency to the lowest mark and turn the pendulum motion off. Workpieces should be firmly clamped. The feed rate must not exceed 30-35% of the maximum feed rate.
The tool is moved smoothly, without pushing or jerking. The trimmer saw blade should be as close to the support as possible. To improve the operating mode and extend the life of the cutting device in the cutting zone, with a metal thickness of 3-6 mm, the length of the cut 10-20 mm, it is advised to add a cooling-lubricating emulsion. If there is a large amount of work to be done, always take a break. to give the jigsaw time to cool down. Sawing metal with it requires a lot of time and patience, this process is quite time-consuming.
When you need a precise cut
Sometimes it is necessary to saw off so that the two elements can be connected with a minimum gap. This is where precise cutting is important. Accuracy of the cut is also needed to make the place of the cut look neat.
To know how to saw with a jigsaw smoothly, there are a few common rules.
How to cut wood, chipboard, plywood
To saw wood and its analogues (chipboard, plywood, fiberboard, laminate, laminated chipboard), you need to use saw blades with a pitch of 3-4 mm and a maximum stroke frequency. The jigsaw should be moved slowly while pressing against the workpiece. If you want to cut quickly, you can use a pendulum motion of the saw blade.
How to cut ceramic, porcelain tile
When working with these materials the tool must never be pushed. For ceramics, hard-alloy blades of a certain length are suitable; for porcelain stoneware, diamond blades are used.
How to cut metal
For such purposes a fine-toothed saw with 1-2 mm pitch, low frequency of movement and without pendulum is used. Only smooth working movements. No pressure on the tool.
How to cut plexiglass, plastic
To saw off this kind of material, a saw with a fine tooth is used. Provided that the pendulum stroke should be set to the minimum value.
- Having a functioning, adjusted jigsaw.
- A solid, rigid work table.
- Securely clamping the workpiece.
- Proper marking.
- Use of additional tooling, if necessary.
- Secure hand grip.
The extensive capabilities of the jigsaw give not only the reality of doing different types of work, but also create problems for beginners. In order for the tool to reveal its variations fully, you need to know how to use it. If you want the lines of the part to come out as planned, you should understand how to saw evenly with an electric jigsaw.
with a box cutter
We enclose the angle to the workpiece, and using a box cutter we cut the fishing line for the trimmer along the sawing area. Then cut the same line for the trimmer on the other side.
The groove that we make must correspond to the thickness of the saw blade.
And then we make a cut with the jigsaw. The result is much better than if you saw without prior preparation.
Marking the sawing line
To evenly cut material with the jigsaw, you must correctly mark the line for the trimmer sawing and firmly fix the workpiece on the surface. If it is necessary to work with a long sawblade, it is necessary to use a flat rail as a guide and two clamps for its fastening and the working material. Proceed in a certain sequence.
The first thing to do is to mark out the chipboard using a ruler. To do this, the required distance is measured from both sides, the marks are connected, forming a line for the trimmer cut. To make a shaped line, it is advisable to draw it on paper and then transfer it to wood with a copying pen, having first sanded the surface.
To cut a circle with the jigsaw, the marks are drawn with a construction pencil or black marker on the surface using a pre-made stencil of thick paper or cardboard. In this case, cutting the material begins by drilling a hole in the center. The blade should move from the center to the marking line, and then around the circumference of the circle.
How to Saw Straight with a Handsaw | Paul Sellers
Important! Jigsaw inherently designed for curvilinear cuts, cutting them straight in a straight line is difficult enough. It is necessary to constantly monitor the line and direct the tool a little to the side.
To avoid chips on the finished surface the saw during the work is led not along the mark, but near it. Laser guide on a jigsaw will help to saw evenly.
How to saw off plywood without scoring
Sawing plywood often leaves scuffs on the surface. But there is a simple way to avoid it.
To do this you just need to glue a Plexiglas plate to a double-sided adhesive tape.
With this kind of overlap on the blade, there will be no scuffing after the cut. You can see for yourself if you look at the photo below.
