Looking for recommendations for 1/16th ballnose and endmll bits?
Are there any bits you could use to engrave in granite or marble?

Russ, unless that thing is made of gold a 1/16th bit isn't worth $61 bucks......at least not to me.

I don't think you will be able to cut Granite with a carbide bit. You may get it to cut marble if the marble is soft.

Centurion tools in Louisa has one for $24. "solid carbide," Don't know if they are intended for granite.

You can use carbide bits on marble, but for granite you need diamond. Most diamond bits intended for stone working require flood coolant, although some can work dry. But any time you're making dust out of hard materials like granite, you're not only risking health issues (silicosis) but you can damage your machine if the delicate sliding parts are not protected with bellows (although Shopbot's vee-wheel system is more tolerant of dust than other kinds of slides). Machines designed for stone work are different from woodworking machines, and need to be hardened against abrasive dust and slurry.
