Faulty Blade

This occurs more often than you think, a blade becomes faulty when a tooth becomes missing, or it has way too many burn marks. This may be a manufacturer’s fault or the blade being damaged during moving and even using the wrong blade for the wrong material.

So it’s best that you always check your blades for any missing teeth to prevent your blade from becoming faulty.

Dull Blade

Using the same blade for long periods will cause the blade to become dull. This happens due to wood pitch collecting on the blade’s teeth, therefore if your blade is not cleaned regularly using a bristle brush, your only solution left will be to change your blade with a new one.

Needing Another Blade Type

This is most probably the most common reason for changing a miter saw’s blade. There are different types of blades with a different number of teeth. These blades are used to make different types of cuts, as well as cutting through various materials. 

For example, carbide-tipped blade is the most expensive type of blades, as they tend to last for a much longer time than their counterparts, while steel blades are the most used type of blades and they are perfect for cutting softwood, and finally, high-speed steel blades are a stronger version of steel blades as they last longer than them and can be used on stronger materials.

6 Steps to Change a Miter Saw’s Blade:

Changing a miter saw’s blade is relatively easy to perform. However, you should always refer to your blade’s user manual to further your understanding of the process and of your saw and blade’s model. The steps to change a blade are:

1. Make Sure Your Saw Is Not Connected To a Power Outlet

This step is a must, as you always need to make sure that your saw is not connected to a power source. Because any mistake while changing the blade can and will be fatal.

2. Remove the Spindle Cover

To remove it, you have to rotate the blade guard to the top, then unscrew the front screw. Finally, the guard will start returning to its normal position and fall by itself, and you will have the blade in front of you.

3. Remove the Blade

This is the step that we all have been waiting for, removing the blade from its socket. You must, first of all, hold down the blade locking pin, it is a black pin on your saw’ right side, then use a wrench to unscrew the blade from its place.

You should always refer to your user manual to know the blade locking pin’s exact location.

4. Installing the New Blade

This is the exact opposite of the previous step. This step is all about directions, and you need to make sure that you match the directions on the blade with the ones on the saw. Another tip to avoid installing the blade in the wrong direction would be to always put the blade with the logo looking upwards.

So all you have to do is to insert the blade and match the directions, then screw in the bolt and tighten it using a wrench (to tighten the bolt rotate the wrench left, while to unscrew it rotate the wrench to the right).

5. Reinstall the Spindle Cover

This is very simple as all you have to do is to place the spindle cover into its place and replace all the screws using a wrench.

6. Try It Out

Before actually using your miter saw to make cuts, you must try it out first to get a grip of the new blade’s strength and speed.

Safety Precautions

Your safety and the safety of everyone around you is of utmost importance, and it must come before anything, that is why we have included some safety precautions that you must follow. They are:

  • Always wear double-layered or triple-layered safety gloves to protect your hands and fingers from the saw’s blade.
  • Wear safety goggles to protect your eyes and even a face mask to cover your face.
  • Remove any jewelry that you are wearing.
  • Try as much as you can to avoid touching the blade’s teeth.
  • Wear overalls to cover your clothes and protect them.
  • Finally, and this is the most important step of them all, you must always make sure that your miter saw is not connected to any power outlet while changing the blade as any mistake can be fatal.

Final Thoughts

Finally, a miter saw is an indispensable tool, and the skill to change its blade is a must for every user. As blades become rusty and dull a lot and you will need to change them often to perform different cuts and cut different materials.
