Now that I’ve explained the probable causes of this issue, it’s time to get to the solutions. After identifying the reason, you have to approach the solution accordingly. Let’s go through each solution in detail.

Clean The Miter Saw

The first and most common reason causing this issue is sawdust. Even when you have an excellent dust collection system for your miter saw, dust can gather inside the miter saw, causing problems.

So, it’s important that you regularly clean the miter saw from the inside out. Now, this is where it gets tricky. Because no two miter saws are alike, opening them won’t be identical to one another.

So, the best solution here is to go through your user manual. The user manual of your miter saw is a guideline on how to tweak the settings and how you can remove different parts. For this particular issue, you only need to expose the head so that you can clean the area around the blade.

There’s a very high possibility that you will see a collection of dust inside the miter saw. Remove the dust and then put your miter saw back together. While you are at it, clean the blade with a cleaner too. Now, check if the issue still exists.

Adjust The Depth Setting

As I have mentioned, you can adjust how deep the cut will be. If you have just bought the miter saw and the material isn’t cutting all the way through, the reason might be this particular feature.While this is an excellent feature to get creative, it can put a strain if you don’t know how to adjust it.

Most of the time, there will be a screw on the miter saw head that adjusts how deep the cut will be. However, it can vary depending on the model you are using. So, it’s important that you check the user manual to see where the depth button is. If you want a visual tutorial for adjusting the depth of a miter saw, you can check this video.

Other Reasons And Fixes

  • A dirty blade can hinder the smooth cutting process. So, make sure to clean the blade when you are getting rid of the dust.
