Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 3/4" x 7" x 13" 48-20-3930

REINFORCED CONCRETE DOMINATION WITH MX4 SOLID HEAD CARBIDE

The Milwaukee MX4 4-Cutter SDS Max bits represent a significant leap in mechanical drilling efficiency, specifically engineered to tackle the high-torque demands of reinforced concrete. By utilizing a solid head carbide design, these bits maintain structural integrity under extreme thermal loads, delivering up to 5x longer life compared to standard tipped bits. The integrated 4-cutter geometry is a critical safeguard against the common failure point of bit lock-up when encountering rebar, ensuring continuous productivity and reducing the risk of tool kickback. For professionals running high-output cordless platforms, the optimized flute geometry facilitates rapid debris extraction, which minimizes friction and allows for up to 15% more holes per battery charge, maximizing jobsite ROI.

• / Solid head carbide construction provides superior durability and up to 5x longer life in hard aggregate and rebar.
• / 4-Cutter geometry prevents binding and lock-up when hitting rebar, protecting both the tool and the operator.
• / Sharp centering tip allows for exact spot drilling, preventing bit walk even on metal decking or smooth concrete.
• / Optimized variable flutes clear dust faster to reduce heat buildup and increase cordless battery efficiency.
• / Wear mark indicators provide a clear visual cue for ANSI B212.15 compliance, ensuring anchor fitment accuracy.
