Milwaukee SDS Plus 4-Cutter MX4 3/16" x 2" x 4" Drill Bit 15 Pack 48-20-7910

DOMINATE REBAR AND HARD AGGREGATE WITH MX4 DURABILITY

When high-volume anchoring in reinforced concrete is the standard, the mechanical failure of a standard bit represents a significant hit to jobsite productivity. The Milwaukee MX4™ 4-Cutter SDS Plus bits are engineered with a solid head carbide that maintains structural integrity even when encountering embedded rebar. Unlike traditional 2-cutter bits that often bind or wander, the 4-cutter geometry ensures a perfectly concentric hole, which is critical for meeting ANSI B212.15 standards for mechanical anchor reliability. Furthermore, the variable flute design optimizes dust extraction, significantly reducing thermal stress on the bit and maximizing the efficiency of your cordless rotary hammers by delivering up to 20% more holes per charge.

• / Solid head carbide construction delivers up to 5X longer life in concrete with rebar compared to standard bits.
• / 4-Cutter design prevents lock-up and binding in rebar, reducing downtime and tool kickback.
• / Variable flute geometry accelerates dust removal, keeping the bit cooler and extending battery runtime.
• / Integrated wear mark indicator provides a visual cue for bit replacement to ensure holes remain within ANSI tolerances.
