Frequently Asked Questions

  • Q: What are diamond burs used for?
    A: Diamond burs are used for carving, engraving, shaping, and detail grinding on stone, glass, ceramic, and gemstone materials. They mount in flex-shaft handpieces, Dremel tools, or rotary tools.
  • Q: Can I use specialized diamond bits in a standard drill?
    A: Most flex-shaft and twist bits are compatible with standard rotary tools and drill presses. Always use water cooling and match the bit shank size to your tool's collet or chuck.
  • Q: What is a step drill bit used for in lapidary?
    A: A step drill bit drills progressively larger diameter holes in a single pass — useful for creating countersunk or stepped holes in thin stone slabs, glass panels, and ceramic tile without changing bits.
