I was crosscutting a piece of Indian Rosewood today. I am absolutely certain that there was no metal in the wood. Nonetheless, my blade put off several noticeable sparks. Can anyone comment on what may be causing this?

Check your blade – may have lost a carbide tooth in the dense rosewood.

Well, I would have a few ideas for you if you had been using a bandsaw, but on the tablesaw can’t think of anything. So, next time you get sparks try to make sure you’re on the bandsaw and I’ll be able to help.

May have been a small piece of gravel grown into the wood.

I hope Topa is right. FWIW – This wood was salvaged in Florida after a hurricane. Maybe, due to the way it was handled, it go an embedded piece of gravel. This piece has 2 natural edges.

I checked my blade and everything looks good.

hey rich, i work with indiam rosewood a lot and some time some board have a lot of sillica sand in them from where they grow. not much you can do about it except be ready. maybe have one set blade just for rosewood so as not to ruin a bunch.
