Top Reddit comments about Power Drill Bit Sharpeners:

A. What are the stones? I will assume they are silicates like Jasper or Agate, but softer is always easier.

B. The diamond bits you got are more for shaping than drilling, and they do not have any pathway for debris removal. A carbide or diamond glass/ceramic bit may work better. Dremel has a high speed one or Home Depot has glass/tile ones that may run a bit more your speed.

C. An 1/8" hole through rock will always break bits. Get lots of bits, go at high speeds, advance slowly and pull out after advancing to flush kerf out of the hole and keep coolant on it. Good luck.
