Frequently Asked Questions

• Q: What is the difference between resin bond and sintered diamond carving burs?
  A: Resin bond burs have diamond particles bonded in a resin matrix — economical and good for general carving on softer stone and glass materials. Sintered burs have diamond embedded throughout the entire bur body — as the surface wears, fresh diamonds are exposed, giving 5–10× longer service life on hard stone and glass. Sintered burs cost more upfront but are significantly more economical for professional and high-volume carving work.
• Q: What shank size do I need for my rotary tool?
  A: 2.35mm shank burs fit Dremel and similar hobby rotary tools. 3mm shank burs fit Foredom flex shaft machines and most professional rotary tools. 6mm shank burs fit standard die grinders and larger professional rotary tools. Always verify your tool's collet size before ordering.
• Q: Should diamond carving burs be used wet?
  A: Yes — always use water cooling when carving with diamond burs. Water prevents heat buildup that can damage both the bur and the workpiece, extends bur life significantly, reduces stone dust, and produces cleaner cuts. Use a water drip system, water swivel adaptor, or work in a shallow water bath.
• Q: What grit bur should I start with for stone carving?
  A: Start with 30–80 grit for aggressive material removal and rough carving, 100–120 grit for general shaping and detail work, and 320–1200 grit for fine detail finishing and surface smoothing before polishing. The 100 grit sintered ball bur set (H012) is the most versatile starting point for general gemstone carving.
• Q: What is the advantage of buying 100pcs bulk packs?
  A: Bulk packs (100pcs) are economical for production carving, jewelry making, and bead drilling where burs are consumed regularly. The per-bur cost in bulk packs is significantly lower than individual or small set purchases — ideal for studios and production environments where the same bur size and grit is used continuously.
