ENGINEERED FOR EXTREME DURABILITY IN REINFORCED CONCRETE

The MX4™ 4-Cutter SDS MAX series represents a significant leap in consumable engineering for heavy-duty anchoring and structural penetration. By utilizing a solid head carbide design, Milwaukee has addressed the primary failure point of traditional bits: rebar strikes. This bit doesn't just survive contact with steel; it is engineered to maintain structural integrity and cutting speed through hard aggregate and rebar, providing up to 5x the service life of standard bits. The 4-cutter geometry is critical for preventing the lock-up that often leads to snapped bits and operator fatigue. Furthermore, the variable flute design optimizes dust extraction, which is essential for reducing thermal stress on the carbide and maximizing the efficiency of cordless SDS MAX hammers. For professionals tracking ANSI compliance for anchor seating, the integrated wear mark indicator provides a clear visual cue for replacement, ensuring every hole meets structural specifications.

• / Solid Head Carbide Construction: Delivers up to 5x longer life in concrete with rebar compared to standard 4-cutter bits.
• / Integrated Rebar Guards: Protects the bit from catastrophic failure and prevents lock-up when encountering steel reinforcement.
• / Sharp Centering Tip: Enables precise spot drilling and prevents walking on smooth concrete or metal decking.
• / Optimized Flute Geometry: Enhances dust removal efficiency, reducing heat buildup and increasing holes per charge on M18 FUEL or MX FUEL platforms.
• / ANSI Wear Mark Indicator: Ensures the bit still meets the required tolerances for secure anchor installation.
