Bosch HCFC2081B25 25 pc. 1/2 in. x 4 in. x 6 in. SDS-Plus® Bulldog™ Xtreme Carbide Rotary Hammer Drill Bits

Product Description 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. From the Manufacturer Extraordinary lifetime and high drilling speed in concrete and concrete with rebars; New centric conical tip - top hole guidance, constant hole diameter; New Sharp cutting edge border - deep penetration into concrete with rebars with each hit - continuous high drill speed. New wear mark - always correct hole diameter for anchor setting.
