Long-lasting SDS-max® drill bit design Å“ manufactured with 100% carbide head and four-cutter design, making it the long-lasting bit for drilling in reinforced concrete and hard aggregate

Latest diffusion-bonding technology Å“ provides 5X life vs. competition, for the strongest bond available

Four-cutter head design Å“ provides 180° cutting diameter and 100% power transfer during drilling

Four symmetrical 90° side angles Å“ create a wide and sharp tip to aggressively cut through tough material like concrete with rebar

Active-centering tip Å“ results in rounder holes for precision-anchoring applications, with a wear mark to help deliver precision hole-diameter tolerance

Bosch-made carbide Å“ advances consistent, quality material; the only concrete bit manufacturer to make its own carbide

Four-flute design Å“ aggressively pull dust away from the work, keeping the bit tip cooler for longer bit life
