MILWAUKEE Hammer drill SDS-Max MX4 SDS-Max, 4 cutting edges, 16 x 540 mm 4-carbide cutting edge from 16 mm drill diameter, with reinforcement chamfers on each cutting edge. Lower vibrations and better drilling performance in armouring irons for a longer service life. Specially developed, robust head geometry with optimum 4 x 90° cutting symmetry. No blocking of the drill if reinforcement is hit. Centring tip with 130° angle. Fast, precise drilling and optimum guidance during drilling. Large, robust minor cutting edge with dynamic cutting edge. Supports the main cutting edge, for faster drilling. Shorter thread. For faster drilling dust removal from the head to spiral, reduced wear and heat generation in the drill head. Wear indicator on both sides of the carbide element. Ensures accurate drilling and dimensionally stable holes throughout the entire service life. Patented core-reinforced spiral (CRS). Low-vibration drilling and extreme break resistance. Impact energy is transferred directly to the drill tip. PGM (Prüfgemeinschaft Mauerbohrer) tested. Guaranteed to create precise dowel holes throughout the entire service life.
