Milwaukee MX4 4-Cutter SDS MAX Rotary Hammer Drill Bit 1-1/2" x 24" x 29" 48-20-3985

REINFORCED CARBIDE FOR UNINTERRUPTED DRILLING IN REBAR

The MX4™ 4-Cutter SDS MAX Rotary Hammer Drill Bit is engineered for the most demanding structural concrete applications where downtime isn't an option. Featuring a solid head carbide design, this bit provides a mechanical advantage when encountering heavy rebar, delivering up to 5x longer life compared to standard tipped bits. The integrated rebar guards act as a shield, preventing the head from shattering upon impact with steel reinforcement. By optimizing the flute geometry, Milwaukee has significantly improved dust evacuation, which reduces friction-induced heat and maximizes the efficiency of your cordless SDS MAX hammers, yielding up to 15% more holes per charge. For professionals maintaining strict adherence to anchor specifications, the wear mark indicator provides a clear visual gauge to ensure every hole remains within ANSI B212.15 tolerances.

• / Solid Head Carbide construction delivers superior durability and up to 5x longer life in rebar-reinforced concrete.
• / 4-Cutter design prevents binding and lock-up when striking rebar, ensuring continuous productivity.
• / Sharp centering tip allows for exact spot drilling, preventing bit walk on hard aggregate or metal decking.
• / Wear Mark Indicators provide a definitive end-of-life signal to maintain ANSI compliance for critical anchor installations.
