Engraving bits for stone?

Hi Boyan

Yes the link provided by Peter are what you will need, I get mine from Aliexpress, so far they have been ok. You will definitely need some flood cooling, lots, try cutting stone without cooling and your bits will be useless after the first job. It is a very very messy job an like peter said rails and gears etc need protecting. also flood cooling is to stop the dust which is lethal to man and machine. Get that dust in your lung and guaranteed silicosis. I also sandblast stone and have an air supplied full mask. Don't think dust extraction will help you.
