Why is my saw blade smoking?

Last Updated: 26th May, 2020

When blades heat up from cutting, they melt the pitch or sap in the wood. This will then get stuck on the blade. When the pitch builds up on the blade, it is harder for the sawdust to clear the cut and then creates more friction. This in turn can leave burn marks and create smoke.

Simply so, why is my miter saw smoking?

The simplest and most common cause for this to happen is that your blade could be getting blunt with usage. This means that the blade cannot easily cut into the wood anymore and it has to struggle and apply a lot more pressure than before.

Additionally, why is my circular saw burning the wood? A Dull or Dirty Saw Blade Might Be the Culprit A dull blade will make it hard to cut quickly, and the slower the feed rate of the saw, the more friction against the wood and the greater the likelihood of scorch marks. Pushing the stock through the saw too slowly is a common cause of saw blade burn.

Thereof, why does my saw get stuck?

If your saw gets stuck on you, it will probably mean that you are not keeping your hand steady and you are bending the blade. When the blade is old, it is suggested you change it or cutting will result in a rougher finishing and it will also take longer.

Why does my circular saw spark?

If the sparks go all the way around the copper strips, also called the commutator, the armature has shorted. That means the insulation between the wires and the iron has broken down in the inside of the armature. Some times it can be as simple as a short between the bars, the copper strips, of the commutator.

Why does my table saw bind?

This can cause the board to bind can lead to cuts that aren't square. Support the work piece and keep pressure against the fence, not the blade.

When should I replace my circular saw blade?

Ways to tell its dull:
  1. it starts binding.
  2. it tears/chips the substance more than usual.
  3. it burns the wood.
