SDS-max rotary hammer bit with Speed-X Technology. Centric tip guides bit through hard and reinforced concrete. Angled dust channels reduce heat build up resulting in longer life. Inclined side cutters provide an aggressive edge for faster cutting. Wear mark identifies when bit has worn to level inappropriate for precision anchoring. Long pitch spiral increases speed and reduces vibration. Bosch rotary hammer bits feature tips (2 cutter tungsten carbide) that stay sharper longer and deliver more holes within their ANSI specification than competitors' bits. SDS-max rotary hammer bits not only fit Bosch SDS-max hammers, but also competitive SDS-max drive hammers and Hilti hammers using TE-Y and TE-FY shanks.
