Heavy drilling with Milwaukee MX4

Practical benefits

No jamming on rebar: The symmetrical 4-cutter head prevents the bit from seizing up when you hit reinforcing steel.
Pinpoint accuracy during startup: The integrated centering point helps you position each hole exactly where needed without slipping on tough surfaces.
Fast removal of debris: Short spiral flutes quickly evacuate drilling dust from the head, reducing heat build-up and bit wear over time.

In a nutshell

The right choise for

Drill deep pass-through holes in reinforced concrete with absolute confidence using the Milwaukee MX4 SDS-max hammer drill bit 4932352781. Featuring an 800 mm working length and a 28 mm diameter, it allows you to tackle deep penetrations through thick walls and foundations for plumbing pipes, electrical conduit, and heavy-duty anchors. The symmetrical 4-cutter solid carbide head prevents jamming when striking rebar while ensuring perfectly round holes for secure fixings. a dedicated centering point provides pinpoint accuracy from the start without slipping on tough surfaces. Its 4-spiral flute design rapidly clears dust and debris, reducing heat build-up and tool wear throughout demanding jobs.

Key features according to our expert

Diameter: 28 mm
Drill bit type: Hammer drill bit
Overall length: 920 mm
Shank type: SDS-max
Material (drill bit): Carbide tip
Number of cutting edges: 4 ea
Cutting length: 800 mm

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.
