Milwaukee SDS Max 4CT MX4™ 7/8" X 12" X 17"

REBAR-STRIKE RESILIENCE

In high-production concrete anchoring, the mechanical failure of a consumable bit represents more than just a replacement cost—it's a complete disruption of the workflow. The Milwaukee MX4 4-Cutter SDS Max series is engineered to mitigate that risk for industrial fleet operators. By utilizing a solid-head carbide geometry rather than traditional brazed tips, these bits maintain structural integrity even when encountering heavy rebar. This design ensures that your large-capacity rotary hammers deliver consistent hole diameters for critical ANSI compliance while maximizing the life of the tool's internal clutch system by preventing sudden lock-ups.

• / Solid-Head Carbide Construction: Engineered to survive direct rebar hits with 5X more durability than standard 2-cutter bits.
• / Symmetrical 4-Cutter Geometry: Minimizes bit binding and provides smoother drilling in reinforced concrete for better operator control.
• / High-Volume Dust Flutes: Optimized spiral design clears spoil rapidly to reduce heat friction and prevent flute clogging.
• / ANSI Wear Mark Indicators: Features a visual gauge on the head to confirm the bit still meets tolerance for drop-in anchor precision.
• / Centering Tip: Eliminates bit walk and ensures immediate hole placement on hard aggregates or metal decking.
