Fast and accurate drilling with the Milwaukee SDS-Plus MX4 hammer drill bit

Practical benefits

Perfect round anchor holes: The symmetrical 4-cutter head prevents jamming against rebar, ensuring you produce exact cylindrical holes for secure anchor fitting.
Efficient dust removal: With the high-volume 4-flute design, you clear masonry debris rapidly while minimizing drilling friction.
Pinpoint starting accuracy: The sharp centering tip allows you to position the bit exactly on target without slipping on hard concrete.

In a nutshell

The right choise for

With the Milwaukee SDS-Plus MX4 hammer drill bit, you drill deep holes through reinforced concrete, solid natural stone, and masonry with complete confidence. The solid carbide 4-cutter head prevents jamming when hitting rebar and ensures perfectly round holes for secure anchor fixings. With an overall length of 450 mm and a working length of 400 mm, you easily penetrate thick walls for pipe feed-throughs, cabling, or heavy threaded rods. The sharp centering tip prevents slipping during startup, while the 4-flute design rapidly clears drilling debris and minimizes vibration on your SDS-Plus rotary hammer.
