Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 48-20-3986

REBAR-CRUSHING STRUCTURAL ENDURANCE

When you're drilling into bridge decks or heavy industrial slabs, hitting rebar isn't just an obstacle—it's a certainty. The Milwaukee MX4™ 4-Cutter SDS Max bits are forged for the absolute brutality of heavy civil job sites, featuring a solid head carbide design that chews through structural steel where standard bits simply melt. This is about maintaining a relentless production pace in the most punishing aggregate, ensuring that your crew stays on schedule even when the substrate is working against you.

• / Solid Head Carbide: Engineered to deliver up to 5x longer life when drilling through reinforced concrete and high-density aggregate.
• / Integrated Rebar Guards: Provides maximum mechanical durability, preventing tip failure and lock-up when the bit encounters buried steel.
• / Sharp Centering Tip: Ensures surgical accuracy for spot drilling on metal decking or uneven masonry surfaces.
• / Variable Flute Design: Optimized for high-speed dust evacuation, reducing thermal buildup and increasing holes-per-charge by up to 15%.
• / Wear Mark Indicators: Provides immediate visual confirmation that the bit still meets ANSI B212.15 requirements for critical anchor tolerance.
