Milwaukee MX4 4-Cutter SDS MAX Rotary Hammer Drill Bit 1/2" x 13" 48-20-8402

REINFORCED CONCRETE DOMINANCE WITH 4-CUTTER CARBIDE PRECISION

When you're drilling into high-PSI concrete laced with rebar, standard bits are a liability. The Milwaukee MX4™ SDS MAX series is engineered for the mechanical stress of heavy-duty rotary hammers, utilizing a solid head carbide design that maintains structural integrity even when striking steel. By integrating rebar guards, this bit eliminates the sudden "catch" that often snaps lesser bits or jars the operator, ensuring a smooth, continuous bore. The optimized flute geometry is a critical efficiency factor for cordless users, as it clears debris faster to reduce friction and thermal buildup, directly translating to more holes per charge on your M18 FUEL or MX FUEL platforms.

• / Solid Head Carbide: Delivers up to 5x longer service life in extreme aggregate and rebar-reinforced concrete.
• / Anti-Lock 4-Cutter Geometry: Prevents bit binding and lock-up when encountering rebar, protecting the tool's clutch and the user's wrists.
• / Sharp Centering Tip: Enables precise hole placement and prevents bit walking on smooth concrete or metal decking.
• / Optimized Flute Design: Removes dust faster to reduce heat and deliver up to 15% more holes per battery charge.
• / Wear Mark Indicators: Provides a clear visual gauge to ensure holes remain within ANSI B212.15 tolerances for critical anchor setting.
