In a nutshell
The right choise for
With the Milwaukee MX4 hammer drill bit, you can drill deep, clean holes through masonry, concrete, and reinforced concrete. Featuring a usable working length of 940 mm and an overall length of 1000 mm, it allows you to complete deep penetrations for cables, wires, or narrow pipes in a single pass. The symmetrical four-cutter head prevents jamming and seizing when striking rebar, while the sharp centring point ensures pinpoint accuracy right from the start without slipping. Meanwhile, the high-volume four-flute design clears dust rapidly to minimize friction and wear. Equipped with an SDS-Plus shank, this 12 mm bit fits any SDS-Plus rotary hammer for smooth, dependable performance.
