Milwaukee 5/16" x 10" x 12" SDS-PLUS 4-Cutter MX4 Drill Bit 48-20-7344

REINFORCED CONCRETE DOMINANCE

When you're managing tool inventory across a multi-trade jobsite, the cost of consumables is only half the story—downtime from jammed bits in rebar is the real profit killer. The Milwaukee MX4™ series is engineered to mitigate that risk, utilizing a solid-head carbide construction that maintains structural integrity when encountering the high-tensile steel hiding in your concrete slabs. Designed for the professional who demands long-term ROI and consistent hole diameter, these German-made bits ensure your anchors seat perfectly every single time.

• / Solid Head Carbide / Provides up to 5X longer life in heavy rebar applications compared to standard tipped bits.
• / Integrated Rebar Guards / Engineered to prevent lock-up and binding when hitting steel, reducing the risk of wrist-snap and tool damage.
• / Sharp Centering Tip / Guarantees exact spot drilling in concrete and metal decking without bit-walk.
• / Variable Flute Geometry / Optimized for rapid dust evacuation, significantly reducing heat buildup and extending battery runtime.
• / Wear Mark Indicator / Provides a clear visual reference to ensure the bit still meets ANSI B212.15 tolerance for anchor fitment.
