Alpen Speedster Crown & Bridge Carbide Bur, #847, Flat End Taper, Friction Grip (FG), 1.40mm Diameter, 5/Pk, RCB847F014

Alpen Speedster Crown & Bridge Carbide Burs feature a one-piece construction that eliminates brazed joint breakage and rusting, combining familiar diamond-bur shapes with durable carbide construction. The #847 modified flat end taper bur with a 1.40mm head diameter is designed for rapid crown and bridge preparation, gross reduction, and removal of amalgam, gold, porcelain, enamel, and PFM. Optimized cutting speed, reduced vibration, dampened chatter, and controlled heat help prevent damage to tooth structure.
