How to Change a Jigsaw Blade – A Quick Guide In 2018

While the jigsaw is a very powerful tool, if you do not have a functional blade, then the tool becomes futile. This is the key reason for learning how to change a jigsaw blade. At one point or another, the blade wears out and this makes the cutting process to be quite difficult. This is the main trigger for blade changes in your jigsaw. If your blade is not sharp, then the quality of the cuts is compromised as well, and as such, you should change blades often.

Some people may recommend sharpening the jigsaw blades, but in my opinion, this is not worth your time. The blades are quite cheap and it will be convenient to buy a new one instead of going through the trouble of sharpening it. Generally, due to the design of the jigsaw blades, you will be forced to change them frequently, especially, if you are professional. You will want to achieve high quality cuts, and this will be impossible, with a faulty blade.

Jigsaw Blade Change Systems

When shopping for a jigsaw, one of the things that I recommend as the features to look for the blade change mechanism. The older models, come with a screw that will hold the blade in place and this is tightened or loosened using Allen key or a screwdriver.

However, there are modern jigsaws that have come into the market and this will have a tool-free blade system. This is quite convenient as you will not need any tools to change the blades. The mechanism will eject the blade from the clamp, by disengaging the level. There are other models that have a spring-loaded lever as well, to eject the blade.

These modern systems are not only effective but also a safety measure. When you are cutting your applications, the blade tends to become hot and can be dangerous to touch. The spring-loaded models will eject the blade and you will not have to touch it, as it is the case with the manual systems.
