Bosch Bulldog Xtreme SDS-plus Rotary Hammer Bits are now optimized for use with cordless power tools based on a robust two-flute design that ensures great speed in dust removal with less potential for binding.
One thing that hasn’t changed about the Bulldog Xtreme line is full-head carbide for bits up to 5/8 inches that delivers 4X life drilling in concrete with rebar, yet offers maximum drilling speed and precision. Advanced geometry ensures performance with less carbide wear. Bits beyond 5/8 inch feature a four-cutter design
The overall flute design of the bit enhances dust removal, reduces operating temperatures and reduces bit stress in concrete and rebar. Full-head carbide bits feature the Velocity flute design: four flutes that transition to two larger flutes for increased dust removal capacity and a cleaner hole. Bosch Bulldog Xtreme bits deliver performance in reinforced concrete or harsh aggregate, plus lightweight and normal weight concrete.
Bosch utilizes a proprietary diffusion-bonding technology, a high-heat, high-pressure solid-state welding process that produces an incredibly strong steel/carbide bond. This gives Bosch Bulldog Xtreme bits
The centric conical tip guides the bit and results in rounder holes, which is important when setting anchors or fasteners. A wear mark alerts the user when the bit has worn to a level where it’s no longer precise. Bit sizes for the full range extend from 3/16 to 1 1/8 inch diameter. The bits will be available starting in April 2017.
