Bosch 7/8" x 10" x 12" SDS plus Bulldog Xtreme Carbide Rotary Hammer Drill Bit

The Bosch SDS-plus® Bulldog™ Xtreme Rotary Hammer Bit is longer lasting, due to its proprietary carbide-bonding technology that provides a stronger bond of the four-cutter head to the bit. The bit provides 4X life in concrete with rebar. The centric conical tip guides the bit, resulting in rounder holes, which is important when setting anchors or fasteners. The four-cutter head design features less carbide wear than two-cutter bits, making the user more productive. A wear mark alerts the user when the bit has worn to a level where it’s no longer precise. With an optimized flute design for cooler operation, the bit delivers performance in reinforced concrete or harsh aggregate, plus lightweight and normal weight concrete.
