1. Longer Cutting Period
Even a semi dull blade cannot handle the pressure of longer cutting periods as it will create excessive friction with the wood and by heating up it may create smoke by rubbing with wood at higher speeds.
2. Damp Wood
Dampness of wood can be a reason for smoke coming from saw while cutting. It is understood that dampness makes wood harder to cut. Saw blades run at high speeds though wood is harder and wet. The hotness of the blade may oxidize the moisture and eventually smoke will come up.
3. Dull Blade
If the blade of your saw is dull, it will never go fluent through the cuts. By running idle, it will develop great friction with the wooden piece, it will produce some heat than smoke and fire hereafter if you keep running it.
4. Filthy Blade
If you have worked for long with your circular saw, by cutting different types of woods, a sticky sort of substance, which is called pitch, will emerge on your circular saw’s blade teeth. By making the blade hard to slice through materials, pitch can also lead circular saw to smoke.
