Milwaukee MX4 SDS-Max Concrete Drill Bit

Large carbide tip with patented chamfered cutting edges. Ensures less vibration and optimized drilling performance when hitting steel reinforcement, extending lifespan.
Specially developed powerful head geometry and optimal 4 x 90° symmetry of the carbide tip. Reduces the risk of jamming when hitting steel reinforcement.
130° centering tip. Easy precision drilling thanks to the centering tip, which ensures optimal guidance during drilling.
Large powerful secondary cutter with dynamic convex cutting edge. Supports the primary cutter, ensuring faster drilling.
Shorter spiral twists. For faster transport of drilling dust from the drill head to the workpiece = less wear and heat on the drill tip.
Innovative unique carbide tip. More carbide for all diameters and additional carbide for ⌀ > 32 mm.
Wear indicator on both sides of the primary cutter. Guarantees diameter accuracy, e.g. when installing anchors. Lifespan indicator in case of warranty.
Patented reinforced drill bit working part geometry. Less vibration allows smoother drilling. Stronger working part means fewer breakages. Better transfer of impact energy to the tip.
Deep working part shoulders. Large amount of dust removal ensures optimal drilling speed, reduces wear and heat generation.
Drilling with less vibration. Comfortable drilling causes less strain on the person and the device.
Special surface treatment. Shot peening ensures a smooth surface, seals the surface structure, and increases the drill bit's wear resistance.
PGM mark. Guarantees precise holes for anchor installation throughout the drill bit's lifespan.
