Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 1" x 16" x 21" 48-20-3954

ENGINEERED FOR REBAR-REINFORCED STRUCTURAL CONCRETE

When your crew is drilling through high-PSI structural concrete and hitting heavy rebar mats, you can't afford bit lock-up or premature tip failure. The Milwaukee MX4 SDS Max bit is built for the high-torque demands of heavy-duty rotary hammers, featuring a solid carbide head that won't shear when it encounters reinforcement. The four-cutter geometry ensures a rounder hole for critical anchor placements, while the optimized flute design manages the massive dust volume generated during 16-inch deep bores, protecting the tool's motor and extending battery life on the rig.

• / Solid Carbide Head: Delivers up to 5x longer life in structural concrete with heavy rebar reinforcement.
• / Integrated Rebar Guards: Engineered to prevent chipping or head failure when striking hard aggregate or steel.
• / 4-Cutter Geometry: Prevents the bit from binding in rebar, ensuring continuous drilling and perfectly round holes for ANSI-compliant anchoring.
• / Optimized Flute Design: Maximizes dust extraction to reduce heat buildup and increase battery efficiency on cordless SDS Max platforms.
• / Wear Mark Indicators: Provides a clear visual reference to ensure the bit still meets ANSI B212.15 tolerances for critical anchor installation.
