Milwaukee SDS Plus 4-Cutter MX4™ 3/8" X 4" X 6" Drill Bit 48-20-7351

REINFORCED CONCRETE DRILLING WITH SUPERIOR CARBIDE LONGEVITY

The Milwaukee MX4™ series represents a significant advancement in rotary hammer accessories, specifically engineered to overcome the mechanical stresses of drilling through hard aggregate and rebar. By utilizing a solid head carbide design rather than a simple inlay, these bits maintain structural integrity under high heat and impact. For professionals operating on cordless platforms, the variable flute geometry is a critical efficiency factor, clearing debris faster to reduce motor strain and extend battery runtime. The inclusion of a wear mark indicator ensures that every anchor set meets ANSI standards, protecting the integrity of the installation and providing a clear metric for tool replacement ROI.

• / Solid Head Carbide Construction: Engineered to deliver up to 5X longer life in concrete with rebar compared to standard tipped bits.
• / 4-Cutter Geometry: Minimizes the risk of bit lock-up when striking rebar, ensuring continuous productivity and reduced tool kickback.
• / Sharp Centering Tip: Provides pinpoint accuracy for exact spot drilling in concrete and metal decking, preventing bit walk.
• / Variable Flute Design: Accelerates dust extraction to keep the bit cooler and deliver up to 20% more holes per battery charge.
• / ANSI Wear Mark: Integrated indicator provides a reliable visual reference for bit replacement to ensure anchor fitment compliance.
