When Should You Replace a Jigsaw Blade?

You should replace a jigsaw blade when it becomes dull , bended, or damaged. As a general rule, it’s a good idea to replace a jigsaw blade after every few uses, or whenever you notice that it’s not cutting as cleanly or smoothly as it used to. This will help ensure that the jigsaw is working at its best and will prevent any damage to the workpiece or the jigsaw itself.

You can recognize a dull saw blade by 4 symptoms that I describe in my article, How Do I Know If My Jigsaw Blade Is Dull (4 Simple Ways). This is definitely worth reading so that you know perfectly when the limit has been reached to replace a jigsaw blade and to keep the quality of your work high.

Be sure you use the right blades

When replacing a jigsaw blade, it is very important to pick a new blade that is not only suitable for the type of material you want to cut , but also for which type of jigsaw the blades should be used. Also keep in mind you choose the right blade for the jigsaw cutting depth you want to use.

There are different types of jigsaw blades that are suitable for cutting wood, plastic, metal, and even ceramic tiles. Festool has the handy color codes yellow for wood, red for plastic, and blue for metal. Well-thought-out by the people at Festool and that is also the reason I am personally such a big fan of this brand.

In addition , you have to be aware of the different types of blades depending on the jigsaw. Some jigsaws can only handle U-shank blades, while in other jigsaws only T-shank blades can be mounted.

The main difference between U-shank and T-shank jigsaw blades is how they can be attached to your jigsaw.

Remember that U-shank blades have a U-shaped slot at the top. These will fits onto a corresponding pin on the jigsaw, while T-shank blades have a T-shaped slot that fits onto a groove on the jigsaw.

U-shank blades are generally considered to be more secure , and less likely to come loose during use, while T-shank blades are easier to remove and replace. T-shank blades are also more commonly used in newer jigsaw models, while U-shank blades are more commonly used in older jigsaws.

Overall, the choice between U-shank and T-shank blades will depend on the compatibility with your jigsaw, changing from brand to brand. It’s generally a good idea to use the type of blade that is recommended by the manufacturer of your jigsaw.

How to change a keyless jigsaw blade

Replacing a jigsaw blade on keyless tools is actually a very simple process which most people can do on their own. To help you with this, I have listed a few simple steps you’ll need to follow (pictures below):

  1. First, unplug the jigsaw. if it is cordless, you better remove the battery. This is a precautionary action to prevent the jigsaw from accidentally turning on while you are working on it and hurt yourself.
  2. Next, Locate the release lever or button on the side of the jigsaw or just above the jigsaw blade. This is the mechanism that holds the blade in place, and you have to push or flip it to remove the old blade.
  3. When the blade release lever is pressed, the blade should come free of the jigsaw. Lift it out carefully, being careful not to touch the blade’s teeth. Please keep in mind that I know from experience that the blade really pops out at Festool, so point it away from you. The benefit is that you don’t have to touch the knife and pull it, potentially injuring yourself.
  4. Then, take the new blade and place it in a notch or groove that fits a matching pin on the jigsaw, so make sure you line it up properly.
  5. Push the blade into the blade mount until it clicks into place after alignment. You may need to use some force to do this or turn the blade a quarter turn like with the festool jigsaws, but be careful not to overload the blade or jigsaw.
  6. Check that the blade is properly seated and that the blade release lever is fully engaged once firmly in place. If everything looks good, you can reconnect the jigsaw or replace the battery and test.

How to Change a Jigsaw Blade That Is Locked in Place with Screws

Some brands, or older models, still rely on screws to keep the blades in place. There is nothing wrong with this; you just need to spend a little more time replacing a jigsaw blade. You must also ensure that the blades are properly installed. I knew that possibility existed with my old jigsaw , which also had this type of clamp. Incorrectly installed blades can cause breakage or other issues.

Below I show you how you can easily replace a jigsaw blade with this type.

  1. First unplug the jigsaw or remove the battery if it is cordless. you don’t want the jigsaw to accidentally turn on while you are working with the saw blade.
  2. Usually you will find a screw, or even two screws,on the head where the jigsaw blade meets the jigsaw. These are often Allen bolts. Loosen it with the appropriate Allen key.
  3. If the bolts are loose enough , the blade will come off. Be careful when you grab the blade and pull it so as not to injure yourself. Usually the upper teeth are still quite sharp and intact.
  4. Then take the new blade and place it in a notch or groove that fits a matching pin on the jigsaw,so make sure you line it up properly.
  5. After checking whether the blade is properly in place , you can tighten the screws until the blade is stuck in its place. If everything looks good, you can plug the jigsaw back in or replace the battery and test.
