Which rotary hammers are compatible with this drill bit?

This drill bit features an SDS-max shank and fits all rotary hammers with an SDS-max chuck. It is not compatible with SDS-plus tools.

What are the dimensions of this hammer drill bit?

The drill bit has a 25 mm diameter, an overall length of 520 mm, and a working length of 400 mm.

Is this drill bit suitable for reinforced concrete?

Yes, the 4-cutter MX4 carbide head allows efficient drilling through concrete and rebar while reducing the risk of jamming.

What is the benefit of a 4-cutter design?

The 4 cutting edges produce precise, circular holes ideal for anchor installation while lowering vibration and jamming.

What is the purpose of the 4-flute design?

The 4-flute geometry quickly removes dust from the hole, reducing heat build-up and bit wear during drilling.

Heavy-duty drilling with Milwaukee

Practical benefits

Reduced jamming in rebar: The symmetrical four-cutter geometry prevents the head from seizing up when you hit reinforcing steel.
Accurate and easy spot-drilling: A sharp 130-degree centring point ensures you start holes with exact precision without slipping.
Rapid dust extraction flutes: Shorter spiral windings transport debris away quickly to reduce heat buildup and wear on the tip.

In a nutshell

The right choise for

With the Milwaukee SDS-Max MX4 hammer drill bit, you drill smoothly and reliably through reinforced concrete and dense masonry. The 4-cutter carbide head with a 130-degree centring point ensures accurate spot-drilling without slipping, while preventing the bit from jamming when hitting rebar. Its 4-flute spiral geometry clears dust and debris rapidly from the hole to reduce friction and heat buildup. Featuring a 25 mm diameter, a 400 mm working length, and an overall length of 520 mm, this drill bit provides the depth and control needed for installing heavy-duty anchors, conduits, and pipe penetrations.

Key features according to our expert

Diameter: 25 mm
Drill bit type: Hammer drill bit
Overall length: 520 mm
Shank type: SDS-max
Material (drill bit): Carbide tip
Number of cutting edges: 4 ea
Cutting length: 400 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.
