Learn Why Your Miter Saw Burns Wood & How to Fix It

If you notice brown scorch marks on the ends of the wood after you cut it with your miter saw or even see smoke coming from the timber as the blade passes through, you may wonder why this is happening.

There are several potential causes for this burning of wood. You may find that the saw is struggling to cut the wood or that you are experiencing tear-out and other signs of a poor cut.

In some cases, you may even set off the fire alarm! No matter the reason, let’s look at why this is happening.

There are several reasons why your miter saw may be burning the wood:

  1. Dull blade: If the edge on your miter saw is light, it may cause the wood to burn as it cuts through the material. This can be due to the blade being worn out or sharpened correctly.
  2. Incorrect blade speed: If the blade speed on your miter saw is too high, it can cause the wood to burn as it cuts through the material.
  3. Incorrect blade depth: If the blade on your miter saw is set too deep, it can cause the wood to burn as it cuts through the material.
  4. Incorrect blade tooth geometry: If the blade on your miter saw has the wrong tooth geometry, it can cause the wood to burn as it cuts through the material.
  5. Incorrect feed rate: If you are pushing the material through the miter saw too quickly, it can cause the wood to burn as it cuts through the material.
  6. Poor quality wood: If the wood you use is of poor quality or has knots or other imperfections, it may be more prone to burning as it is cut.

To prevent burning the wood using a miter saw, use a sharp, high-quality blade, set the blade depth and speed correctly, and feed the material through the saw at a moderate pace.
