Milwaukee 3/4" x 8" SDS Plus MX4 4-Cutter Masonry Drill Bit 48-20-7210

ULTIMATE CONCRETE PENETRATION

In the high-stakes world of jobsite productivity, few things derail a timeline faster than a snapped masonry bit or an oversized hole that won't take an anchor. The Milwaukee MX4™ series represents the pinnacle of rotary hammer engineering, specifically designed to withstand the brutal forces of high-PSI concrete and internal rebar reinforcement. This isn't just a bit; it's an insurance policy against downtime, ensuring every hole is drilled to exact ANSI specifications with the speed required for large-scale fastener installations and structural retrofitting.

• / SOLID HEAD CARBIDE: Engineered to deliver up to 5X more life in concrete with rebar compared to standard 2-cutter masonry bits.
• / SYMMETRICAL 4-CUTTER HEAD: Prevents seizing and binding when encountering rebar, protecting both the tool's internal clutch and the operator from sudden kickback.
• / REINFORCED FLUTE GEOMETRY: High-volume variable flutes optimize dust extraction for cooler running temperatures and significantly increased drilling speeds.
• / WEAR MARK INDICATOR: Provides a clear, necessary visual cue for when the bit no longer meets ANSI B212.15 anchor installation standards.
• / SHARP CENTERING TIP: Eliminates bit walking on smooth surfaces, allowing for immediate and precise hole placement in critical layout applications.
