The fischer hammer drill bit SDS Max II/ IV are high-quality drill bits with 2 or 4 carbide cutting edges and SDS-Max chucks. The SDS Max drill chuck ensures optimum transfer of force and allows for rapid drilling progress for large volume and deep drill holes. The hammer drill bits are characterised by the innovative product features of the fischer Hammer drill bits Quattric and Pointer. The PGM®-conform cutting element guarantees the creation of approval-compliant drill holes. The quadruple flute reliably transports the drilling dust from the drill hole, thus reducing wear.
