Milwaukee SDS Plus 4-Cutter MX4™ 3/16" X 10" X 12" Drill Bit 48-20-7314

PRECISION ANCHORING THROUGH REINFORCED CONCRETE

When drilling deep into hard aggregate or hitting rebar, the mechanical integrity of the bit determines jobsite productivity. The MX4™ series is engineered for high-volume anchoring where downtime from bit lock-up or heat-related failure is not an option. By utilizing a solid head carbide and a 4-cutter geometry, these bits maintain structural stability even when encountering steel reinforcement. The variable flute design is a critical efficiency factor, clearing dust rapidly to prevent frictional heat buildup, which directly translates to more holes per charge on cordless rotary hammers and a higher professional ROI through extended tool life.

• / Solid head carbide construction provides 5X longer life in high-stress rebar-reinforced concrete applications.
• / 4-cutter geometry prevents binding and lock-up when hitting steel, protecting the user and the tool's clutch mechanism.
• / Variable flute geometry optimizes dust extraction, reducing thermal load and increasing holes per battery charge by up to 20%.
• / Integrated wear mark indicator provides a visual gauge for ANSI compliance, ensuring anchor pull-out strength remains within specification.
