High-performance Milwaukee SDS-Max bit

Practical benefits

Solid four-cutter carbide tip: The 4-cutter symmetrical geometry prevents jamming when hitting rebar, keeping you drilling smoothly without sudden stops.
Extreme drilling depth: With an overall length of 1320 mm, you can easily drill through thick walls and solid concrete.
Fast dust extraction: The 4-flute design rapidly channels debris away from the tip to reduce heat buildup and maintain drilling speed.

In a nutshell

The right choise for

With the Milwaukee SDS-Max MX4 hammer drill bit, you can easily drill large penetrations through solid brickwork, natural stone, and reinforced concrete. Featuring a 1200 mm working length and an overall length of 1320 mm, it allows you to create deep 40 mm holes in a single pass, ideal for running substantial pipes and ducts. The solid 4-cutter carbide head with a 130° centering point delivers accurate spot drilling and prevents jamming or breakage upon hitting rebar. Meanwhile, the 4-flute spiral geometry rapidly extracts heavy drilling dust to minimise heat build-up and sustain high drilling speeds, ensuring total control throughout heavy-duty jobs.

Cutting length: 1200 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.
