Diamond wheel. Diamond wheels are grinding wheels with industrial diamonds bonded to the periphery. They are used for grinding extremely hard materials such as carbide cutting tips, gemstones or concrete. The saw pictured to the right is a slitting saw and is designed for slicing hard materials, typically gemstones.
The grinding wheel should be 200 to 400 fine grit. Make a saddle block with a 118 degree transverse angle groove at a 15 degree up sweep. Clamp the block to the bit stop on the bench grinder. Put the drill in the block with the point not in contact with the stone. Put on your safety glasses and start the grinder. In one smooth motion, move the drill bit up to lightly contact the stone and rotate the bit as you increase pressure slightly.
