SDS Speed Extreme Hammer Bit 1" x 16" x 21"

Engineered for the toughest jobs, the SDS Speed Extreme Hammer Bit delivers exceptional durability and performance in reinforced concrete and hard aggregate. Its 100% solid-carbide head is bonded to the steel shaft using proprietary diffusion-bonding technology, providing up to 5× the life of standard bits. Designed for SDS-max rotary hammers, this bit stands up to demanding applications and cuts through material with unmatched speed and precision.

With a four-cutter tip and four-flute design, the Speed Extreme Hammer Bit maintains 100% power transfer while aggressively removing dust to keep the bit tip cooler and extend service life. The active-centering tip ensures accurate starts and rounder holes for precision anchoring, even when drilling through concrete with rebar.
