The fischer hammer drill bit SDS Max IV 22/400/520 is a high-quality drill bit that is ideal for drilling large volume and deep holes in concrete, masonry, and natural stone. It features a SDS-Max chuck that ensures optimum transfer of force and rapid drilling progress. The drill bit is also characterized by its innovative product features, including the Quattric and Pointer cutting elements. The Quattric cutting element has 4 carbide cutting edges that provide a smooth, clean cut, while the Pointer cutting element helps to prevent the drill bit from wandering. The PGM-conform cutting element guarantees the creation of approval-compliant drill holes, and the quadruple flute reliably transports the drilling dust from the drill hole, thus reducing wear.
