Advice on jigsaws
1. What will you be cutting?
Thanks to the maneuverability and the fine saw, a jigsaw is very suitable for sawing in corners. This can be useful if you want to saw a hole for the sink in the kitchen top. Cutting through PVC pipes or rounding corners is also done with a jigsaw. But you also use this type of sawing machine to let your creativity run wild, for example for jigsaws. You can make doll houses, wooden puzzles, letters or other decorative objects with a jigsaw.
2. Want to make straight cuts?
There is a good chance that you will not only want to use your sawing machine for cutting bends and circles, but also to make neat and straight cuts. Although a jigsaw is less suitable for this, it is certainly not impossible. Certain skirting boards, laminate and frames can be easily worked with a jigsaw. If you attach a straight piece of wood - or conductor - with a clamp to the workpiece to be cut, you can hold the base of the jigsaw against it. Saw slowly along the guide and you are assured of a straight cut.
3. How do you handle fine sawing jobs?
In the more specialized sawing jobs you should think of making a bird house, soapbox or other toys. To bring this to a good end result, there are a number of things to look out for. If the jigsaw has a tilting footplate, it is possible to cut in a corner or 'in miter'. This can be useful for sawing skirting or sheet material for furniture at an angle so that you then connect 2 parts seamlessly.
4. What is pendulum device?
Jigsaws can have multiple pendulum positions. Each material has its own ideal pendulum position. In this position the saw not only moves up and down, but also from front to back. This makes the saw 'bite' through the material, as it were. This way you work faster and you make longer cuts. In general, the harder the material, the lower the pendulum position. In fine material, working with the pendulum position can result in a sloppy result. You have less control and splinters can occur at the bottom of the cut.
5. What is the ideal cutting speed?
Usually the jigsaw is provided with 'variable speed'. You then keep yourself in control of the cutting speed. This speed is expressed in 'strokes per minute'. It may sound logical, but for the sake of certainty we will repeat the most important rule of thumb: slow cutting helps you work accurately and neatly. Also in hard material it is wise to cut at low speed, so you avoid unsightly damage. You use the highest speed for wood and sheet material. Apart from the material, it is advisable to start slowly with sawing, and speed up as soon as you are on the right cutting line.
6. How much power do you need?
Like any power tool, jigsaws differ in power and wattage. If you are going for a powerful jigsaw of (more than) 600 watts or 18 volts, then it is suitable for the heavier jobs such as cutting through hardwood or metal sheets. If you plan to use the jigsaw frequently, a higher power is also recommended. From 400 watts or 10.8 volts, the most common jobs are fine.
7. Which blade do you use?
Some jigsaw blades are specifically designed for cutting sharp turns, so you can accurately saw figures from wooden planks. These are slightly narrower than the standard variant. To determine the correct length of a saw blade, use a simple sum: the width of the material to be cut + 80 millimeters = the ideal length of the saw. Another rule of thumb that is useful to remember: no matter what you saw in, make sure that there are 3 teeth in contact with the material to be cut at all times.
Coarse or fine
The number of teeth of the saw blade is also relevant. The more teeth, the finer the finish. For hard materials it is best to use a saw blade with many teeth. The lower the number of teeth, the better the sawing result is in soft materials. Usually, the saw blade indicates which wood species it is suitable for, so you do not have to look for it yourself. Depending on the saw blade, it is possible to saw in different materials such as wood, metal, plastic or plastic. The saw blades for wood have coarser teeth than those for metal. You use saws with finer teeth also for plastic or plastic.
T or U shaft
There is a distinction between saws with a T-shaft and with a U-shaft. This is not called by chance: the ends of the saws resemble either a letter T or a letter U. The T-shaft is the most common type, but a large part of the jigsaws is suitable for both variants. Check this to make sure that you are sure that the saw blade will fit.
8. Mains or battery
Are you going for a jigsaw that works on battery or on mains power? On battery, and therefore cordless, offers more freedom of movement. You do not need an extension cord when you get to work in the garden and you do not have to worry about accidentally cutting the cord. On the other hand, jigsaws on batteries usually have less power and are therefore less suitable for sawing harder materials. You can also be obstructed in your work by a battery that is empty and needs to be charged before you can continue. So the choice for you.
9. Extra convenience
If the jigsaw has a clamping system, you can change the saws without the need for tools. Handy! During sawing it is inevitable that the sawdust flies in the round. If the sawing machine has a blower function, the sawdust is blown away from the cutting line, so that you have a good view of your work. If the jigsaw has the possibility of dust extraction, simply connect a vacuum cleaner to this, so that the sawdust is cleaned up immediately. Built-in LED lighting is also a handy aid to see where the cut is coming. Finally, most jigsaws have a softgrip handle, so that the blisters are not in your hands during prolonged work.
