MILWAUKEE SDS-Max 4-cutter drill bits

Large cutting edge with beveled corners. Ensures less vibration and optimal drilling performance in reinforced concrete applications. Longer bit life over time;4 x 90° head geometry. Allows precise holes and excellent drilling performance, even in the presence of rebar;130° Primary cutting edge.The 130° cutting edge angle,allows optimal performance during applications in the presence of rebar and excellent hole accuracy;Secondary cutting edge. Robust to support the primary cutting edge during drilling, for faster drilling;Short groove for better dust extraction and for faster drilling speed, less wear and less heat buildup;Groove located to the side of the primary cutting edge, allows you to check bit wear. Milwaukee guarantees its bit up to 75 m;Reinforced bit section. This allows for less vibration, less breakage and better transfer of tool power to the bit;Deep groove shoulder. This allows for more and faster dust extraction and less heat buildup on the drill head and thus less wear;Less Vibration. Comfortable drilling with less stress on the user and the tool;Special surface treatment. For smoother powder flow over the drill head surface and less friction;PGM mark. Ensures precise and accurate holes and maximum dowel hold
