Milwaukee SDS Max 4CT MX4™ 1-3/8″ X 18″ X 23″

STRUCTURAL REINFORCEMENT DOMINANCE

When you’re pushing high-torque rotary hammers into bridge decks or structural footings, you need a bit that eats steel for breakfast. The Milwaukee MX4 SDS Max series is built for the heavy civil environment where 5,000 PSI concrete and high-yield rebar are the baseline. This isn’t just a consumable; it’s a mission-critical component designed to survive catastrophic strikes and maintain hole diameter integrity for critical epoxy and mechanical anchors in the most punishing conditions on the jobsite.

• / Solid Head Carbide / Delivers up to 5x more life than standard cutters when faced with dense concrete and heavy rebar reinforcement.
• / Integrated Rebar Guards / Specifically engineered to shield the bit from fracturing or seizing upon direct contact with structural steel.
• / Sharp 90-Degree Centering Tip / Provides surgical accuracy for spot drilling, preventing bit-walk on sloped surfaces or reinforced metal decking.
• / Optimized Variable Flute Geometry / Expedites dust removal to lower internal friction and heat, maximizing the efficiency of your high-torque hammer.
• / ANSI Wear Mark Indicators / Visual confirmation that the bit continues to meet critical tolerances for code-compliant anchor installation.
