Milwaukee SDS Plus MX4 4-Cutter 7/8" x 6" x 8" Drill Bit 48-20-7225

MAXIMUM REINFORCED CONCRETE ENDURANCE

When you are managing heavy-duty fleet operations, the consumable is often the bottleneck in production. The Milwaukee MX4 series is engineered to eliminate that liability by utilizing a solid-head carbide design that maintains structural integrity under extreme thermal loads. Unlike standard bits that shear when meeting structural steel, these 4-cutter bits are designed to navigate rebar without the lock-up that damages tool transmissions and stalls work schedules. For the professional seeking the lowest cost-per-hole and maximum uptime, the MX4 represents the pinnacle of German-engineered masonry performance.

• / SOLID HEAD CARBIDE: Engineered for up to 5X longer life compared to standard bits when drilling through high-PSI concrete and rebar.
• / ANTI-LOCK REBAR GUARDS: Specialized geometry prevents the head from seizing in steel, protecting the operator and the rotary hammer's clutch.
• / VARIABLE FLUTE GEOMETRY: Rapidly evacuates debris to reduce friction, delivering up to 20% more holes per charge on cordless platforms.
• / WEAR MARK INDICATOR: Provides a clear visual reference for ANSI B212.15 compliance, ensuring holes remain within tolerance for critical anchor fitment.
• / CENTERING TIP: Aggressive point prevents bit walking on metal decking or smooth aggregate for precise hole placement.
