Milwaukee SDS MAX hammer drill 22x520

Large carbide cutting edge with reinforcing chamfers on each cutting edge end. Lower vibration and better drilling performance in reinforcing bars for longer tool life. Specially developed, robust head geometry with optimal 4 x 90° cutting edge symmetry. No jamming of the drill bit in case of reinforcement hits. Centimeter tip with 130° angle. Fast, pinpoint drilling and optimum guidance during drilling. Large, robust secondary cutting edge with dynamic cutting edge. Supports the main cutting edge for faster drilling progress. Shorter helix for faster drill dust transport from the head to the helix, less wear and heat generation at the drill head. Innovative, optimized carbide main cutting edge. Wear indicator on both sides of the carbide element. Guaranteed precision-fit drilling and dimensionally accurate drill holes over the entire service life. Patented, core-strengthened spiral. Low-vibration drilling behavior and extreme breakage resistance. Impact energy is transferred directly to the drill tip. Large-volume spiral for faster drill dust transport, faster drilling progress, and long tool life. Low-vibration drilling for high user comfort. Special surface treatment for increased resistance. PGM tested.
