Heavy drilling with the Milwaukee hammer bit

Practical benefits

Jamming resistance in rebar: The solid 4-cutter head geometry prevents the bit from locking up when you hit reinforcing steel.
Pinpoint accurate spot drilling: The sharp 130° centering tip ensures you start holes precisely without wandering across hard concrete.
Rapid dust extraction flutes: Deep flute channels clear debris efficiently to reduce friction and heat build-up over deep drilling depths.

In a nutshell

The right choise for

With the Milwaukee SDS-Max MX4 hammer drill bit, you tackle deep penetrations in solid and reinforced concrete with ease. The symmetrical 4-cutter solid carbide head prevents jamming when striking reinforcing steel. a sharp 130° centering tip ensures precise spot drilling without wandering on hard surfaces. Featuring a 30 mm diameter, an 800 mm working length, and a total length of 920 mm, this bit provides the reach needed for thick walls, foundation slabs, and large utility installations. The 4-flute design rapidly clears heavy dust and debris, reducing friction so you maintain fast, controlled progress with your SDS-max rotary hammer.

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.
