Elevate your rotary hammer performance with the Bosch SDS Speed Extreme Hammer Bit. Built for the toughest concrete-with-rebar applications, this 3/4″ diameter, SDS-max bit delivers industry-leading durability and precision. Its full-carbide, four-cutter head combined with proprietary diffusion-bonding technology provides up to 5× the life of standard bits, while the active-centering tip ensures accurate starts and round holes every time.
