Milwaukee SDS Plus 4-Cutter MX4 1-1/8" x 16" x 18" Drill Bit 48-20-7256

ELIMINATE LOCK-UPS IN REBAR-REINFORCED CONCRETE

When drilling deep anchors into hard aggregate, the mechanical failure of a standard bit often occurs the moment it strikes rebar. The Milwaukee MX4™ SDS Plus series is engineered to solve this specific jobsite bottleneck. Featuring a solid head carbide and a precision-engineered 4-cutter geometry, this bit maintains a consistent drilling path without the violent binding or lock-ups common in 2-cutter designs. The variable flute geometry optimizes the physics of dust extraction, significantly reducing thermal friction and allowing your rotary hammer to deliver up to 20% more holes per charge by minimizing motor strain. This is a high-ROI consumable designed for maximum uptime in the most demanding masonry applications.

• / Solid Head Carbide construction delivers up to 5X longer life when encountering rebar in hard aggregate.
• / 4-Cutter design prevents binding and lock-up, protecting the user and the tool's internal clutch.
• / Sharp centering tip ensures exact spot drilling, preventing bit walk on concrete or metal decking.
• / Integrated wear mark indicator provides a visual reference for ANSI B212.15 anchor fitment compliance.
• / Variable flutes accelerate dust removal, reducing heat buildup and extending battery runtime.
