20mm Wheel Shape Sintered Diamond Bur, 5pcs – 6mm Shank for Stone, Glass & Ceramic

The 20mm Wheel Shape Sintered Diamond Bur (5-Piece Set) is an industrial-grade precision tool engineered for slotting, grooving, edge profiling, and aggressive stock removal on ultra-hard materials.

Unlike standard electroplated burrs that wear down once the top abrasive layer is stripped, sintered diamond tools feature diamond abrasive particles bonded uniformly throughout the solid metal matrix. As the head wears during heavy-duty lapidary and carving work, fresh diamond crystals are continuously exposed, providing exceptional longevity and reliable cutting consistency.
