SDS Plus 4CT MX4™ 5/16" X 4" X 6"

Milwaukee 48-20-7341 — Product Description

The Milwaukee 48-20-7341 SDS Plus 5/16" x 4" x 6" MX4™ Drill Bit is a high-performance rotary hammer bit designed for fast, accurate drilling in concrete, brick, block, and reinforced concrete with embedded rebar.

Built with Milwaukee’s MX4™ solid carbide 4-cutter head, this bit delivers excellent durability and cutting efficiency in hard aggregate. The four-cutter geometry improves hole precision, reduces binding, and significantly increases performance when drilling into reinforced concrete compared to standard 2-cutter bits.

Its centering tip allows for precise spot drilling, while the breaker-point carbide geometry helps aggressively fracture material for faster penetration. The optimized flute design efficiently removes dust and debris, reducing heat buildup and improving drilling speed and tool life.

The 5/16-inch diameter makes it ideal for light-to-medium anchor applications, and the 4-inch working depth (6-inch overall length) provides controlled drilling for standard installation tasks in structural or overhead conditions.
