INFRASTRUCTURE-GRADE CONCRETE PENETRATION

When you are facing down high-PSI reinforced concrete on a heavy civil site, a standard bit is a liability. The Milwaukee MX4 4-Cutter SDS Max bit is engineered for sheer survival in the most hostile environments where downtime isn't an option. Built with solid head carbide, these bits are designed to chew through heavy rebar and high-density aggregate without the catastrophic lock-up that sidelines lesser equipment. For operators running MX FUEL or M18 FUEL rotary hammers, the optimized variable flute geometry doesn't just clear spoils faster—it extracts maximum runtime, delivering the durability required for bridge decks, foundations, and heavy industrial slabs.

• / SOLID HEAD CARBIDE: Provides up to 5x longer life in high-tensile rebar and extreme aggregate conditions compared to standard tipped bits.
• / REBAR GUARD DESIGN: Integrated protection prevents bit binding and catastrophic failure when encountering embedded steel reinforcement.
• / SHARP CENTERING TIP: Eliminates bit walk and ensures exact hole placement even on sloped surfaces or metal decking.
• / ANSI WEAR INDICATOR: Visual wear marks confirm the bit still meets ANSI B212.15 requirements for critical anchor setting accuracy.
• / OPTIMIZED FLUTE GEOMETRY: Engineered for faster dust removal, reducing heat buildup and extending bit life during deep-hole drilling.
