8mm Bullet Shape Sintered Diamond Bur, 5pcs – 6mm Shank for Stone, Glass & Ceramic

The 8mm Bullet Shape Sintered Diamond Bur (5-Piece Set) is an industrial-grade precision tool engineered for detailed carving, contouring, deep groove routing, and aggressive material removal on ultra-hard materials.

Unlike surface-plated tools, sintered burs feature diamond abrasive particles bonded throughout the entire solid metal matrix. As the tool wears, fresh diamond crystals are continuously exposed, delivering up to 10x longer service life and consistent cutting performance under heavy-duty carving and lapidary conditions.
