Milwaukee 9/16" x 4" x 6" SDS Plus 4-Cutter MX4 Carbide Drill Bit 48-20-7381

EXTREME AGGREGATE ENDURANCE

Maximizing jobsite productivity begins with eliminating the downtime caused by failed consumables. The Milwaukee MX4 SDS Plus 4-Cutter series is engineered specifically for industrial-scale anchoring, where rebar encounters are a statistical certainty rather than a possibility. By utilizing a solid-head carbide matrix, this bit maintains its structural integrity and dimensional accuracy far longer than standard brazed-tip alternatives, ensuring that every 9/16" hole drilled remains ANSI-compliant for critical structural fasteners and chemical anchors.

• / SOLID HEAD CARBIDE: Provides exceptional thermal resistance and tip retention when boring through high-PSI concrete and embedded rebar.
• / REBAR GUARD GEOMETRY: Specifically designed to deflect and withstand lateral steel impacts, preventing the catastrophic tip shearing common in 2-cutter designs.
• / CENTERING TIP PRECISION: Delivers surgical accuracy on smooth masonry surfaces, preventing bit-walk and ensuring exact layout adherence.
• / OPTIMIZED 4-FLUTE SPIRAL: Rapidly evacuates dust and debris to reduce friction and minimize heat buildup, directly extending the motor life and runtime of your cordless rotary hammers.
• / ANSI WEAR MARK: Integrated visual indicator ensures you never install an anchor in an out-of-spec hole, maintaining strict compliance with engineering and safety standards.
