Bosch SDS-max® 7/8"D 8" Wild Bore® Rotary Hammer Bit

Model HC5040

Bosch carbide rotary hammer bits feature tips that stay sharper longer and deliver more holes within their ANSI specification than competitors bits. Also, Bosch shafts wear at a much slower rate than most others and can take more abuse because of Bosch's technologically advanced conditioning process
Wild-Bore™ is a specially formulated Tungsten Carbide which provides superior wear resistance in tough applications
Quadro-X™ is a patented Four-Cutter tip design that provides optimal performance when drilling larger diameter holes in masonry materials. This aggressive tip design is more effective when hitting rebar

Manufactured to ANSI standards, Bosch bits also meet and exceed ISO (International Standards Organization) standards. 98% of the carbide tips are molded to the specific ANSI size. Only 2% (specials) of all bit diameters are ground to size
SDS-max® rotary hammer bits not only fit Bosch SDS-max® hammers, but also competitive SDS-max® drive hammers and Hilti hammers using TE-Y and TE-FY shanks
Updated tip and head design provides 15% faster removal rate and 30% longer life
Main cutter is fully embedded in the drill bit body for top power and imapct transmission
Secondary cutters are not connected to the main cutters, eliminating tensioning in carbide, for a longer life
