With the Dewalt DT9546-QZ Extreme 2 hammer drill bit, you drill deep holes through thick walls and tough structures with confidence. Featuring an overall length of 600 mm and a working length of 550 mm, it is built for running cables, conduit, plumbing lines, or creating deep anchor fixings. The durable carbide tip with 2 cutting edges powers cleanly through concrete, stone, and masonry, while the hardened steel body resists breakage under heavy loads. An optimized flute design rapidly clears debris, keeping your drilling fast and steady on any rotary hammer with an SDS-Plus chuck.
