Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 48-20-3953

REINFORCED CONCRETE DOMINANCE

When your crew is tackling bridge decks or high-rise foundations, the margin for error disappears once you hit structural rebar. The Milwaukee MX4™ SDS Max series is engineered for the pure survival of the bit in high-stress aggregate environments. By utilizing a solid-head carbide design rather than a standard brazed tip, we ensure that the thermal spikes generated by high-torque rotary hammers won't lead to catastrophic failure, keeping your heavy-duty fleet operational on the most demanding civil engineering projects.

• / SOLID HEAD CARBIDE: Forged for maximum endurance in high-density concrete, providing up to 5x more life than standard tipped bits under extreme friction.
• / REBAR GUARD DESIGN: Integrated geometry prevents the bit from binding or fracturing when encountering structural steel reinforcement, protecting both the operator and the hammer.
• / SHARP CENTERING TIP: Eliminates bit walk and ensures precision placement for critical anchor bolts in cured concrete and metal decking.
• / ENHANCED FLUTE GEOMETRY: Optimizes dust removal at high speeds, reducing heat buildup and preserving the mechanical efficiency of cordless MX FUEL or M18 hammers.
• / ANSI WEAR MARKS: Provides a clear visual indicator to ensure every hole meets the precise tolerances required for ANSI B212.15 safety anchor installation.
