Milwaukee SDS Plus 4-Cutter MX4 1/2" x 10" x 12" Drill Bit 48-20-7374

MAXIMUM DURABILITY FOR REBAR-REINFORCED CONCRETE

When your crew is drilling hundreds of holes for drop-in anchors or rebar doweling, bit failure isn't just an inconvenience—it's a massive hit to your labor budget. The Milwaukee MX4 4-Cutter SDS Plus bit is designed to mitigate the primary cause of bit failure: rebar strikes. By utilizing a solid head carbide and integrated rebar guards, this bit resists the shearing forces that typically snap standard 2-cutter bits. The variable flute geometry is a critical mechanical upgrade, optimizing dust evacuation to keep the head cool and reducing the drag on your rotary hammer's motor, which translates directly to more holes per charge on your M18 FUEL platform.

• / Solid head carbide construction delivers up to 5X longer life in high-PSI concrete and rebar-heavy slabs.
• / 4-cutter geometry prevents the bit from locking or binding when encountering structural steel, reducing kickback risk.
• / Sharp centering tip eliminates bit walk on smooth concrete or metal decking for precise hole placement.
• / Integrated wear mark indicator provides a visual reference to ensure holes remain within ANSI B212.15 tolerances for critical anchor seating.
