Milwaukee SDS Plus 4CT MX4™ 1/4" X 6" X 8"

MAXIMUM DURABILITY FOR HIGH-VOLUME CONCRETE ANCHORING

When you're drilling hundreds of holes for drop-in anchors or rebar doweling, the mechanical failure of a single bit can stall an entire crew. The Milwaukee MX4 series is engineered to solve the "lock-up" problem common with standard 2-cutter bits when they strike reinforcement steel. By utilizing a solid head carbide and integrated rebar guards, these bits maintain structural integrity under high heat and heavy impact. The variable flute geometry is a critical efficiency factor; it clears dust rapidly to prevent binding and reduces the thermal load on your rotary hammer’s motor and battery, significantly extending your runtime per charge on cordless platforms.

• / Solid Head Carbide: Delivers up to 5X longer life when encountering rebar compared to standard masonry bits.
• / 4-Cutter Geometry: Prevents the bit from seizing or locking up when striking rebar, ensuring user safety and reducing downtime.
• / Variable Flute Design: Optimized dust extraction reduces heat buildup and allows for up to 20% more holes per battery charge.
• / Wear Mark Indicator: Provides a visual gauge for ANSI B212.15 compliance, ensuring every hole drilled meets the required tolerances for secure mechanical anchors.
