STRUCTURAL CONCRETE PENETRATION SUPREMACY

When you're boring through high-PSI structural slabs or reinforced bridge decks, you cannot afford a bit that binds the second it kisses #5 rebar. The Milwaukee MX4™ series represents a paradigm shift in masonry penetration, engineered specifically for the brutal reality of heavy civil infrastructure where down-time on an SDS MAX rotary hammer equates to lost margin. This isn't just a drill bit; it's a precision-ground solution for navigating the densest aggregate and steel reinforcement on the jobsite.

• / Solid Head Carbide Construction: Delivers up to 5x longer life in extreme concrete-with-rebar applications compared to standard bits.
• / Integrated Rebar Guards: Engineered to deflect and withstand steel contact, preventing catastrophic bit lock-up and protecting the tool's internal clutch.
• / Sharp Centering Tip: Enables exact spot drilling on smooth concrete or metal decking, eliminating bit walk for pinpoint accuracy.
• / Optimized Variable Flutes: Accelerates debris removal and reduces heat buildup, providing up to 15% more holes per charge on M18 FUEL or MX FUEL platforms.
• / Wear Mark Indicators: Provides clear visual confirmation of ANSI B212.15 compliance, ensuring every anchor hole meets critical safety tolerances.
