Milwaukee SDS Plus 4-Cutter MX4™ 3/16" X 4" X 6" Drill Bit 48-20-7311

REINFORCED CONCRETE DOMINANCE WITH MX4 CARBIDE TECHNOLOGY

The Milwaukee MX4™ series represents a significant mechanical leap in rotary hammer consumables, specifically engineered to eliminate the primary failure point in masonry drilling: rebar strikes. By utilizing a solid head carbide design rather than a standard brazed tip, these bits maintain structural integrity under extreme thermal loads. The 4-cutter geometry is critical for professional installers, as it prevents the bit from binding or "locking up" when encountering high-tensile steel reinforcement, ensuring a consistent 1:1 hole ratio even in hard aggregate. Furthermore, the variable flute geometry optimizes dust extraction, which directly correlates to reduced friction and lower operating temperatures, extending the runtime of cordless SDS Plus platforms by up to 20% per charge.

• / Solid Head Carbide construction delivers up to 5X longer life in heavy-duty concrete and rebar applications.
• / Advanced 4-Cutter geometry prevents lock-up in rebar, reducing tool kickback and downtime.
• / Variable flute design accelerates debris removal, delivering more holes per battery charge by reducing mechanical resistance.
• / Integrated wear mark indicator provides a visual reference for ANSI B212.15 compliance, ensuring precise hole diameters for critical anchor seating.
• / Sharp centering tip allows for immediate spot drilling accuracy on concrete and metal decking surfaces.
