Deep drilling with Milwaukee

Practical benefits

Solid four cutter carbide head: The balanced geometry prevents lock-up when you hit steel rebar in reinforced concrete.
Fast debris and dust removal: Optimized spiral flutes transport dust away quickly, reducing heat buildup during heavy drilling tasks.
Accurate and clean centering: The 130° point angle gives you exact spot drilling without wandering across smooth surfaces.

In a nutshell

The right choise for

Tackle deep, heavy-duty drilling with total confidence using the Milwaukee 4932352782 SDS-Max MX4 hammer drill bit. With a working length of 1200 mm and an overall length of 1320 mm, it allows you to create 28 mm through-holes in thick reinforced concrete, masonry, and natural stone in a single pass. The solid 4-cutter carbide head prevents jamming when hitting steel rebar, while the 130° centering point delivers pinpoint accuracy without wandering. Thanks to the 4-spiral flute design, drilling dust is cleared rapidly to reduce heat buildup, ensuring smooth, precise, and dependable progress on demanding jobs.

Product description

Large carbide tip with patented rebar chamfers. Ensures lower vibration and optimised drilling performance when hitting reinforced steel equalling longer life time.
Especially developed robust head geometry with optimum 4 x 90° symmetry of carbide tip. Reduces jamming up on hitting reinforcing steel.
Centering point with 130° point angle. Easy spot drilling with pinpoint accuracy and ensures optimum guidance during drilling.
Big, robust secondary cutter with dynamic, curved cutting edge. Supports the primary cutter for faster drilling.
Shorter spiral windings. For faster transport of drilling dust from the head to the flute = Less wear and heat build up at the tip.
Innovative, unique carbide tip. With more carbide on all diameters and extra carbide on Ø >32 mm.
Wear mark on both sides of primary cutter. Guarantees diameter accuracy i.e. for anchor fittings. Life time indicator in warranty cases.
Patented reinforced flute geometry. Lower vibrations for smoother drilling. Stronger flute means less breakages. Better transfer of hammer energy to the tip.
Deep flute shoulders. High volume dust removal for optimum drilling speed less wear and heat build up.
Low vibration drilling performance. Comfortable drilling ensures less stress for man and machine.
Special surface treatment. Shot blasting provides a smooth surface and densifies the surface structure and makes the bit more wear resistant.
PGM conformity. Guarantees precise holes for anchor fitting over the entire life time of the drill bit.
