Milwaukee SDS Plus 4CT MX4™ 7/8" X 16" X 18"

ELIMINATE LOCK-UPS AND MAXIMIZE HOLE PRODUCTION IN REINFORCED CONCRETE

When drilling deep into high-PSI concrete, hitting rebar is the ultimate test of a bit's mechanical design. The Milwaukee MX4™ 4-Cutter SDS Plus bit is engineered to eliminate the common failure points of standard bits. By utilizing a solid head carbide and integrated rebar guards, this bit doesn't just survive rebar strikes—it maintains structural integrity and prevents the dangerous lock-ups that cause downtime. The variable flute geometry is a critical enhancement for cordless efficiency, clearing debris faster to reduce thermal friction and allowing your rotary hammer to deliver up to 20% more holes per battery charge. For the professional, this translates to a higher ROI through extended bit life and significantly reduced labor costs per hole.

• / Solid head carbide construction provides up to 5X longer service life in heavy-duty concrete and aggregate applications compared to standard bits.
• / Advanced 4-cutter geometry prevents bit binding and lock-up when encountering rebar, ensuring continuous productivity and improved user safety.
• / Precision-ground centering tip enables exact hole placement on concrete and metal decking, eliminating bit walk during the initial engagement.
• / Variable flute design optimizes dust extraction to reduce heat buildup and increase drilling speed, delivering more holes per charge on M18 FUEL platforms.
• / Integrated wear mark indicator provides a clear visual cue for ANSI B212.15 compliance, ensuring critical anchor setting reliability.
