Collection: Diamond Convex Carving Wheels

Professional diamond convex carving wheels for grinding grooves, channels, and concave recesses in stone, glass, and ceramic materials. The rounded convex profile is ideal for undercutting, channel carving, bead making, and creating decorative grooves in lapidary and stone carving work — delivering precise, controlled material removal in tight contours. Available in 6" and 8" diameters with multiple profile widths. Always use with water cooling.

Frequently Asked Questions

• Q: What is the difference between a convex and concave carving wheel?
  A: A convex wheel has a rounded outward profile used to grind grooves and channels into stone — the wheel face curves outward, cutting into the material to create a concave recess. A concave wheel has an inward curved profile used to shape the exterior dome of cabochons and curved surfaces. Both are complementary tools in stone carving and lapidary work.
• Q: Can convex carving wheels be used for bead making?
  A: Yes — convex wheels are commonly used to grind the groove around stone beads and to shape the exterior profile of drilled beads. Select a profile width that matches the desired bead groove dimensions. Narrower profiles (1/8"–1/4") suit fine bead grooves; wider profiles (1/2"–3/4") suit larger decorative channels.
• Q: What profile width should I choose for channel carving?
  A: Choose a profile width that matches the desired channel width in your finished piece. Narrow profiles (1/8"–1/4") produce fine detail grooves; medium profiles (1/2") suit standard decorative channels; wide profiles (3/4") are used for broad undercutting and large channel work.
• Q: Should diamond convex wheels be used wet?
  A: Always use water when operating diamond convex carving wheels. Wet grinding prevents overheating, extends wheel life significantly, and produces cleaner, more precise cuts in stone and glass. Never run diamond carving wheels dry.
• Q: What grit convex wheel should I start with for stone carving?
  A: Start with 60–80 grit for aggressive material removal and initial channel cutting, progress to 120–220 grit for detail shaping and bead groove refinement, and finish with 280–600 grit for smooth groove surfaces before polishing.
