Frequently Asked Questions

  • Q: Which wheel type should I choose for cabochon shaping?
    A: Nova resin soft wheels are the most popular choice - the flexible resin bond conforms to curved surfaces, reducing chipping. Use 60-140 grit for shaping, 280-600 for smoothing, and 1200-50000 for pre-polish.
  • Q: Resin bond vs sintered metal bond - which do I need?
    A: Resin bond wheels suit most lapidary gem materials with smooth, consistent cutting. Sintered metal bond wheels offer maximum durability for very hard gems like corundum, topaz, and beryl.
  • Q: Do I need water cooling?
    A: Yes - always use water cooling to prevent overheating, extend wheel life, reduce dust, and produce cleaner grinding results.
