Heavy-duty drilling in reinforced concrete

Practical benefits

Symmetrical Milwaukee four-cutter design: Symmetrical cutting edges prevent jamming when hitting rebar and produce perfectly round holes for secure anchor fixings.
High-volume debris extraction: You clear dust rapidly from deep holes thanks to the four-flute spiral geometry that reduces friction.
Accurate spot drilling control: The solid carbide centering tip prevents slipping on hard surfaces, letting you start every hole precisely.

In a nutshell

The right choise for

With the Milwaukee SDS-Plus MX4 hammer drill bit, you tackle heavy-duty drilling in masonry, concrete, reinforced concrete, and natural stone with complete confidence. The solid carbide head with four symmetrical cutting edges creates clean, perfectly round holes for structural anchors and chemical fixings while preventing jamming when hitting rebar. An integrated centering tip ensures you start each hole with pinpoint accuracy without slipping on hard surfaces. Featuring a 32 mm diameter, a 450 mm total length, and a 400 mm working length, it easily handles deep through-holes for conduit and piping. The high-volume four-flute spiral rapidly clears heavy drilling dust to reduce friction and maintain smooth drilling progress.
