How to Keep a Jigsaw Blade from Bending

There are a lot of things you can do to prevent your jigsaw blades from bending. Let’s go over some of the best ways to keep your jigsaw blades straight and working as they should!

1) Make sure you are using the proper blade for the job.

Blades come in different shapes, sizes, and tooth counts, making them right or wrong for certain applications. For example, if you were cutting metal with a jigsaw, your best option would be to use diamond blades because they have incredibly sharp teeth that cut through material like butter!

2) Store your blades properly.

When you store your jigsaw blades, make sure to keep them in a cool, dry place and out of direct sunlight because heat can cause the blade’s temper to become brittle, which will lead it easily cracking or bending over time!

3) Keep your blades sharp.

When you use a dull blade, the teeth will not cut into the material as easily, which leads to more strain on the blade and can cause it to bend or crack much easier! You should sharpen your jigsaw blades regularly with a proper abrasive wheel for best results!

4) Use a slower feed rate.

Using a slow feed rate allows more time for the blade teeth to cut into the material, which leads less strain on your blades! You should always try to use as slow of a speed as possible when cutting material with your jigsaw because it will decrease wear and tear on your tool while increasing its lifespan!

5) Use a guide.

When you use a guide with your jigsaw, it will help to keep the blade from bending or twisting while also making sure that your cuts are nice and straight! Some people even prefer using guides over their own hands because they can get more control of the material being cut which allows for better accuracy when cutting different shapes out of different materials!

What You Should Do When Your Blade Bends

If you find that one of your jigsaw blades has bent, here’s what you should do: 

Off Your Jigsaw

First and foremost, make sure you shut off the tool and wait for it to stop spinning before touching anything.

Clean It Off

Once you’ve turned the saw off, take a moment to carefully clean any excess material from around it. This will help prevent accidents later on as well as provide better visibility for your next steps!

Straighten Out The Blade

Place one hand over the best part of the blade and hold onto it firmly with your hand. With the other, carefully pull on the non-bent end of the blade to straighten it out.

Fix It

After you’ve done this, take some pliers or a screwdriver and bend that part back into place so it’s nice and flat again! Make sure you do both sides of the bent part evenly so you don’t have a lopsided blade.

Reinstall And Test It Out!

Once your bent jigsaw blades are nice and flat again, reinstall them back into the saw and give it another go to make sure everything is working properly. If all looks good, then you should be ready to get right back to work! 


The jigsaw blade can be bent or damaged due to the number of ways that it is used. If you follow these steps, your blades will last longer and function properly without bending!
