Collection: Diamond Resin Soft Grinding Wheels

Professional Nova flexible resin bond diamond soft grinding wheels for lapidary bench grinders. The flexible resin bond conforms slightly to curved stone surfaces during grinding — reducing chipping and producing smoother results on cabochon domes compared to rigid hard wheels. Available in 6"×1-1/2", 8"×1-1/2", and 8"×2" sizes across a full grit range from 60 to 50,000, including economical 4-grit and 6-grit sets for complete workflow setups. Fits standard 5/8", 3/4", and 1" arbor bench grinders and lapidary machines. Always use with water cooling.

Frequently Asked Questions

• Q: What is the difference between Nova resin soft wheels and diamond flat hard wheels?
  A: Nova resin soft wheels use a flexible resin bond that conforms slightly to curved stone surfaces during grinding — ideal for cabochon dome shaping where the wheel needs to follow the curved profile of the stone. Diamond flat hard wheels use a rigid resin bond that maintains a perfectly flat grinding face — better for flat surface grinding and slab face work. For cabochon shaping, use soft wheels; for flat surfaces, use hard wheels.
• Q: What grit sequence should I use for lapidary cabochon shaping?
  A: Start with 60–140 grit for rough shaping and aggressive material removal, progress to 280–325 grit to refine the dome profile, 600–1200 grit for pre-polish smoothing, 3000–8000 grit for fine pre-polish, and 14000–50000 grit for near-mirror pre-polish before moving to a felt or leather polishing pad with diamond compound for final mirror finish.
• Q: What is the difference between Nova and REZ resin soft wheels?
  A: Both use flexible resin bond construction suitable for cabochon shaping. Nova wheels cover the complete grit range from 60 to 50,000 for full shaping-to-pre-polish sequences. REZ wheels use a premium bond formulation optimized for specific grit stages. Both are compatible with the same arbor sizes and lapidary machines.
• Q: Are the 4-grit and 6-grit sets worth buying over individual wheels?
  A: Yes — the sets offer significant savings over buying individual wheels and provide a complete workflow sequence in one purchase. The 4-grit set covers the core shaping stages (typically 60, 280, 600, 3000 grit), while the 6-grit set extends the range for finer pre-polish stages. Sets are ideal for new setups or when building out a complete cabochon grinding sequence.
• Q: Do resin soft wheels require water cooling?
  A: Yes — always use water cooling when grinding with resin bond diamond wheels. Water prevents heat buildup that damages the resin bond, extends wheel life significantly, and produces cleaner grinding results by flushing away stone swarf. Never run resin bond wheels dry.
