Milwaukee MX4 4-Cutter SDS MAX Rotary Hammer Drill Bit 48-20-8416

REINFORCED CONCRETE DOMINANCE WITH MX4 CARBIDE TECHNOLOGY

When your jobsite requires drilling through high-PSI concrete laced with heavy rebar, the Milwaukee MX4 4-Cutter SDS MAX bit is the mechanical solution for maximum uptime. Featuring a solid head carbide design, these bits are engineered to withstand the extreme thermal stress and impact energy of high-output rotary hammers. The integrated rebar guards act as a structural shield, preventing the head from shattering or binding when encountering steel reinforcement. By optimizing the flute geometry, Milwaukee has significantly improved dust extraction efficiency, which directly translates to cooler operating temperatures and up to 15% more holes per charge on cordless platforms like the M18 FUEL or MX FUEL systems.

• / Solid Head Carbide construction delivers up to 5x longer life in heavy-duty concrete and rebar applications.
• / 4-Cutter geometry prevents lock-up and binding when hitting rebar, reducing tool kickback and user fatigue.
• / Sharp centering tip ensures exact spot drilling, preventing bit walk on smooth concrete or metal decking.
• / Wear mark indicators provide a clear visual gauge to ensure holes remain within ANSI B212.15 tolerances for critical anchor placement.
