Milwaukee 3/8" x 4" x 6" SDS Plus 4-Cutter MX4 Drill Bit 10-Pack 48-20-7951

ELITE REINFORCED CONCRETE PENETRATION

When your crew is staring down a deck full of rebar and hard aggregate, the Milwaukee MX4™ series represents the pinnacle of rotary hammer efficiency. These 3/8" SDS Plus bits are engineered with a solid head carbide design that doesn't just survive rebar strikes—it dominates them. By integrating advanced variable flute geometry, we've optimized dust extraction to keep head temperatures low, ensuring that every M18 FUEL™ or M12 FUEL™ battery charge yields significantly higher hole counts for your fleet.

• / Solid Head Carbide construction provides up to 5X longer life in high-stress rebar-embedded concrete applications.
• / 4-Cutter geometry prevents the bit from locking up or binding when hitting steel, protecting the user and the tool.
• / Precision Centering Tip ensures exact hole placement on metal decking or smooth concrete surfaces.
• / Integrated Wear Mark Indicators provide a clear visual signal for ANSI B212.15 compliance and mechanical anchor integrity.
• / Variable Flute Design accelerates debris removal to increase drilling speed and reduce thermal degradation of the carbide.
