Milwaukee MX4 4-Cut SDS MAX Hammer Drill Bits

4-Cut tip geometry delivers best performance in reinforced concrete and ensures round holes.

Large carbide tip with patented rebar chamfers ensures lower vibration, optimised drilling performance and longer life when hitting reinforced steel. 

Specially developed robust head geometry with optimum 4 x 90° symmetry of carbide tip reduces jamming when hitting reinforcing steel.

Centering point with 130 point angle ensures easy spot drilling with pinpoint accuracy and provides optimum guidance during drilling.

Robust secondary cutting edge supports the primary cutter for faster drilling.

Shorter spiral windings for faster transport of drilling dust from the head to the flute ensures less wear and heat build up at the tip.

Wear mark on both sides of primary cutter guarantees diameter accuracy for anchor fittings – life time indicator in warranty cases.

Patented reinforced flute geometry ensures lower vibrations for smoother drilling. The stronger flute means less breakages and better transfer of hammer energy to the tip.

Deep flute shoulders give high volume dust removal for optimum drilling speed less wear and heat build up. 

Suitable for drilling general masonry including brick, block, concrete, reinforced concrete and natural stone.

PGM marked for guaranteed exact sized drilling holes to ensure anchor specifications are not compromised.
