Description

Tackle demanding drilling tasks with the Milwaukee MX4 4-Cutter SDS-PLUS Rotary Hammer Drill Bit. Designed for high performance in reinforced concrete and masonry, this professional-grade bit combines durability and efficiency to deliver reliable results on the jobsite. The solid carbide head construction enhances strength and provides extended tool life, even when drilling through concrete with embedded rebar.

A precision centering tip allows accurate starting points for clean, controlled drilling, while the 4-cutter carbide design helps prevent binding when encountering rebar, reducing interruptions and improving productivity. The bit also features optimized flute geometry that quickly removes debris from the hole, lowering heat buildup and increasing drilling efficiency.
