Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 48-20-3942

MAXIMUM AGGREGATE DESTRUCTION

When your crew is tasked with high-volume anchoring into reinforced slabs, the difference between profit and loss often comes down to the quality of your consumables. The Milwaukee MX4™ 4-Cutter SDS Max bit is engineered for the industrial fleet, where downtime due to rebar lock-up isn't just an inconvenience—it's a massive hit to your schedule. This bit utilizes a solid-head carbide construction that maintains structural integrity even under the intense thermal loads of continuous drilling in high-PSI concrete.

• / SOLID HEAD CARBIDE: Integrated four-cutter geometry ensures consistent hole diameters, vital for post-installed anchor compliance and long-term fastener security.
• / REBAR GUARD PROTECTION: Precision-engineered guards prevent the bit from seizing or snapping upon contact with steel, protecting your rotary hammer's transmission and the user's wrists.
• / OPTIMIZED 4-FLUTE DESIGN: Efficiently evacuates dust and debris from the hole to minimize heat buildup and extend the service life of the carbide tip.
• / WEAR MARK INDICATORS: Allows for real-time inspection of bit health to ensure every hole meets the exact ANSI tolerances required for safety-critical structural connections.
• / GERMAN-ENGINEERED DURABILITY: Forged to withstand the intense thermal cycles of high-speed drilling in 5,000+ PSI concrete without compromising structural integrity.
