SDS Plus 4CT MX4™ 3/16" X 4" X 6"

The SDS Plus 4CT MX4™ 3/16" x 4" x 6" Drill Bit is a compact, high-performance masonry bit engineered for fast, accurate drilling in concrete, brick, and block—especially in applications where precision anchor placement is required.

Built with Milwaukee’s MX4™ 4-cutter carbide head, this bit delivers excellent durability and stability when drilling through reinforced concrete, including light rebar contact. The four-cutter design helps maintain a round, accurate hole while reducing binding and improving overall control during drilling.

A breaker-point tip aggressively fractures material for faster penetration, while optimized flute geometry efficiently removes dust and debris to keep the bit cooler and maintain consistent drilling speed. The reinforced body helps reduce vibration and increases durability under repeated impact use.

The 3/16" diameter is commonly used for light-duty anchoring applications such as Tapcon-style fasteners, and the 4" usable length (6" overall length) provides controlled depth for standard masonry installations.
