REINFORCED CONCRETE DOMINANCE WITH 4-CUTTER CARBIDE TECHNOLOGY

When you're drilling 3/4" holes for heavy-duty anchors in reinforced concrete, the mechanical failure of a standard 2-cutter bit isn't just an inconvenience—it's a productivity killer. The Milwaukee MX4™ 4-Cutter SDS PLUS bit is engineered to eliminate the common "lock-up" that occurs when hitting rebar. By utilizing a solid head carbide design with integrated rebar guards, this bit maintains structural integrity under extreme heat and torque. The variable flute geometry is a critical mechanical advantage for cordless users, as it optimizes dust extraction to reduce friction, effectively delivering up to 20% more holes per charge on M18 FUEL™ platforms. For professionals requiring strict adherence to anchor manufacturer specifications, the integrated wear mark indicator provides a clear visual gauge to ensure the bit still meets ANSI B212.15 requirements.

• / Solid Head Carbide construction delivers up to 5x longer service life in heavy aggregate and rebar applications.
• / 4-Cutter geometry prevents binding and lock-up when encountering steel reinforcement, reducing tool kickback.
• / Variable flute design accelerates debris removal, lowering operating temperatures and extending battery runtime.
• / Sharp centering tip allows for precise hole placement on smooth concrete or metal decking without bit walk.
• / ANSI B212.15 compliance ensures accurate hole diameters for consistent mechanical anchor performance.
