Milwaukee 1/2" x 12" x 17" MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 48-20-3903

DOMINATE REBAR-REINFORCED CONCRETE WITH 4-CUTTER PRECISION

When your jobsite demands high-volume drilling through hard aggregate and heavy rebar, standard bits simply won't cut it. The Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit is engineered with a solid head carbide that delivers up to 5x longer life in the most demanding concrete applications. Unlike traditional bits that seize or snap upon hitting reinforcement, the integrated 4-cutter design and specialized rebar guards prevent lock-up, ensuring continuous productivity and reduced tool strain. This bit is a mechanical masterclass in dust management, featuring optimized flutes that evacuate debris faster to reduce heat and maximize the number of holes you can sink per battery charge.

• / Solid head carbide construction provides superior durability and up to 5x longer life in concrete with rebar.
• / 4-Cutter geometry prevents the bit from binding or locking up when encountering structural steel.
• / Sharp centering tip allows for exact spot drilling, preventing bit walk on smooth concrete or metal decking.
• / Wear mark indicators provide a clear visual cue for ANSI compliance, ensuring your anchor holes remain within tolerance.
• / Optimized flute design significantly reduces heat buildup and delivers up to 15% more holes per charge on cordless platforms.
