High endurance Milwaukee MX4 hammer drill bit

Practical benefits

Reduced jamming in rebar: The symmetrical 4-cutter head geometry helps you drill smoothly through reinforced concrete without sudden lock-ups.
Fast and clean dust removal: Deep flute channels quickly extract dust from the hole, minimizing friction, heat buildup, and premature wear.
Accurate and low-vibration drilling: The sharp centering tip and reinforced flute core give you pinpoint guidance and comfortable, stable operation.

In a nutshell

The right choise for

With the Milwaukee SDS-Max MX4 hammer drill bit, you drill quickly and confidently through reinforced concrete and solid masonry. The robust 4-cutter carbide head prevents jamming when striking steel rebar, keeping your work moving without sudden lock-ups. Featuring a 35 mm diameter, an 800 mm working length, and an overall length of 920 mm, it lets you create deep penetrations for large pipes or heavy-duty anchors. The sharp centering tip delivers pinpoint accuracy, while the 4-spiral flute design rapidly clears dust to reduce heat buildup and wear, giving you smooth, low-vibration drilling and complete control.

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.
