The patented carbide tip head takes 80% of the workload, ensuring higher durability, speed and rebar performance. The 53° drilling head design means more aggressive cutting and faster dust removal for overall faster performance and the four-cutter tips for less vibration,
faster drilling, rounder holes and better anchoring.

The shank fits all SDS-max rotary hammers.
