Milwaukee SDS Plus 4-Cutter MX4 3/4″ x 16″ x 18″ Drill Bit 48-20-7220

REINFORCED CONCRETE DOMINANCE WITH MX4 TECHNOLOGY

When drilling deep into structural concrete, hitting rebar isn’t just an inconvenienceit’s a potential bit-killer. The Milwaukee MX4 SDS Plus 4-Cutter bits are engineered to solve the “lock-up” problem that plagues standard 2-cutter bits. By utilizing a solid head carbide and integrated rebar guards, this bit maintains its structural integrity even when encountering heavy reinforcement. The variable flute geometry is a critical mechanical advantage, clearing dust more efficiently to prevent heat buildup, which translates directly to more holes per charge on your cordless rotary hammers and a significantly higher professional ROI.

• / Solid head carbide construction provides up to 5X longer life in high-PSI concrete and rebar-heavy slabs.
• / 4-cutter design eliminates binding and lock-up when striking rebar, protecting the user and the tool’s clutch from sudden torque spikes.
• / Variable flute geometry optimizes dust extraction, reducing friction and heat for up to 20% more holes per battery cycle.
• / Integrated wear mark indicator provides a visual gauge for ANSI B212.15 compliance, ensuring anchor holes are drilled to precise tolerances.
