Milwaukee MX4 SDS Max 4-Cutter Rotary Hammer Drill Bit 48-20-3964

MAXIMUM REBAR REINFORCED ENDURANCE

When you're punching holes in bridge decks or commercial foundations, hitting rebar isn't a possibility—it's a guarantee. The Milwaukee MX4™ SDS Max 4-Cutter bit is engineered for the pure survival of your workflow in the most aggressive aggregate environments. By utilizing a solid head carbide design, these bits don't just survive rebar strikes; they dominate them, ensuring your high-torque rotary hammer keeps moving without the catastrophic lock-ups that kill productivity on a heavy civil jobsite. This isn't just an accessory; it's a critical component for maintaining high-volume production in reinforced concrete.

• / Solid Head Carbide: Delivers up to 5x longer life in high-stress concrete with rebar applications.
• / Integrated Rebar Guards: Provides maximum durability in hard aggregate to prevent premature head failure.
• / 4-Cutter Geometry: Eliminates lock-up when hitting steel, reducing downtime and protecting the operator.
• / Precision Centering Tip: Ensures exact spot drilling and prevents bit walk on metal decking.
• / Optimized Flute Design: Clears debris at an accelerated rate to reduce friction and thermal build-up.
• / Wear Mark Indicators: Provides clear visual confirmation that the bit still meets ANSI anchor requirements.
