Bosch Bulldog HCFC2064 Hammer Drill Bit, 3/8 in Dia, 12 in OAL, Variable Flute, 2-Flute, 3/8 in Dia Shank

The Bosch SDS Plus Bulldog™ Xtreme rotary hammer bit provides 4X life in concrete with rebar, due to its 100% full-carbide tip design and proprietary diffusion bonding technology.

The Bulldog™ Xtreme bit provides 25% more holes per charge, with an upgraded variable flute design - four flutes transition to two flutes for fast dust removal. Its centric conical tip results in rounder holes for precision anchoring and it has a wear mark that helps to assure accuracy of the hole.
