Accurate drilling with Milwaukee SDS-Plus MX4

Practical benefits

Perfectly round drilled holes: The symmetrical four-cutter geometry prevents jamming in rebar while ensuring precise holes for secure anchor fixings.
Fast dust extraction: The high-volume four-flute design removes debris quickly, reducing heat buildup and friction as you drill.
Precise spot drilling: The sharp centering tip prevents slipping so you can position your holes accurately on concrete surfaces.

In a nutshell

The right choise for

With the Milwaukee SDS-Plus MX4 hammer drill bit, you drill smoothly and accurately into masonry, stone, and reinforced concrete. The symmetrical four-cutter geometry with a carbide tip prevents jamming when striking rebar, producing round 22 mm holes for secure mechanical and chemical anchor fixings. a sharp centering tip lets you start drilling precisely without wandering across hard concrete surfaces. Meanwhile, the four-flute design removes dust and debris efficiently, reducing heat and friction to maintain fast drilling progress. With an overall length of 250 mm and an effective working length of 200 mm, this SDS-Plus bit delivers the dependable performance needed for conduit penetrations and demanding site installations.
