Is there a drill bit made of the material of grinding wheel of orbital grinder, which breaks down slowly as it drills, or maybe it can be made of like diamond -studded metal file, so that the drill grinds as it drills, instead of cutting through the metal? Thank you for your interest.

Roll? As in moves before it bites into the material? Sounds like you need a center punch.

As far as efficiency goes, I don't see how grinding off the material is more efficient than cutting it, which is what normal drill bits do. Or maybe slice? Shave?
