Milwaukee 5/8" x 12" x 17" MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 48-20-3917

ENGINEERED FOR EXTREME DURABILITY IN REINFORCED CONCRETE

The Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bits represent a significant leap in masonry drilling technology, specifically engineered for the high-torque demands of modern cordless and corded rotary hammers. Featuring a solid head carbide design, these bits provide up to 5x longer life when navigating the high-stress environment of concrete with rebar. The integrated rebar guards are a critical mechanical safeguard, preventing the bit from binding or snapping upon impact with steel reinforcement. By optimizing the flute geometry, Milwaukee has significantly improved dust extraction efficiency, which not only reduces thermal buildup but also maximizes battery ROI by delivering up to 15% more holes per charge on M18 and MX FUEL platforms.

• / Solid head carbide construction delivers superior structural integrity and up to 5x longer service life in hard aggregate.
• / Advanced 4-cutter geometry prevents lock-up and binding when encountering rebar, reducing tool downtime and user fatigue.
• / Sharp centering tip ensures precision spot drilling, eliminating bit walk on smooth concrete or metal decking surfaces.
• / Wear mark indicators provide a clear visual gauge to ensure holes continue to meet ANSI B212.15 requirements for mechanical anchor fitment.
• / Optimized variable flutes accelerate dust removal, enhancing drilling speed and increasing holes per battery charge by 15%.
