Improper Blade Alignment

If the blade is not aligned perfectly, it can cause the throat plate and blade to stay in improper proportion. Whether you’ve gotten a new miter saw or replaced the blade with a new one, proper alignment is the key to preciseness. You can never get accurate measurements on your workpieces if the blade is not set properly.

How you can align your miter saw can vary depending on the brand and the model. So, the best solution in this situation is to check the user manual of your specific model to see how to adjust the blade.

How To Make A Zero Clearance Throat Plate

Some Tips To Remember

Tips and Tricks Saw School
  • Regardless of what you are fixing on your miter saw, make sure that’s not connected to the power source.
  • Avoid using a bent or blunt blade on your miter saw. It’s not only ineffective in cutting in accurate measurement but also causes kickbacks and compromises your safety.
  • If you are having difficulty using the miter saw, troubleshoot the issue and fix it before using it again. Power tools can be dangerous and cause sudden injuries if any of the safety features are missing.
  • Do not attempt to fix any part of the miter saw if it’s still under warranty. Instead, contact the manufacturer to get the issue fixed.

What does the throat plate do on a miter saw?

Many users don’t understand the function of the throat plate on their miter saws and attempt to use the tool without this part. As small as the component is, it plays an important role in ensuring that the miter saw functions effectively.

What does a zero clearance insert do on a miter saw?

A zero clearance kerf plate ensures that the gap is reduced between the edges. When the gap is broad, pieces of wood can get inside through the gap. In addition, it also reduces tear-out because there’s almost no space between the blade and the split. The less space there is, the better your cutting experience will be.

So, if you have a damaged insert on a miter saw, it’s time to replace it with a zero-clearance insert.
