3/16" x 6-1/2" Full Carbide Head SDS+ Concrete Bit

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. Diffusion bonding’s high-heat, high-pressure solid-state welding produces an incredibly strong bond. In internal tests, these bits delivered 4X life in concrete with rebar than a standard SDS-plus® bit. 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.
