Bosch Bulldog Xtreme SDS-plus rotary hammer bits now feature a robust two-flute design that assures great speed in dust removal with less potential for binding.The Bulldog Xtreme bit line has a full-head carbide design for bits up to 5/8 inch, delivering 4X life drilling in concrete with rebar, yet offers maximum drilling speed and precision.
Advanced geometry assures performance with less carbide wear. Bits beyond 5/8 inch diameter 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.
“Drilling in concrete is tough work for the user and the power tool,” said Tom Grego, product manager, accessories, Robert Bosch Tool Corporation. “Using an optimized accessory speeds up the job, saves wear on the tool and assures the best end result – a hole that’s precise. With less potential for binding, users can get more done in less time.”
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 superior strength and a full-head carbide tip that won’t break off when the work gets tough in any concrete or aggregate application. 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 inch to 1 1/8 inch diameter. For U.S. users, this tool should be used in accordance to the OSHA silica regulations designed to limit silica dust exposure, as well as the owner’s manual.
