Sygma industrial grade impact torsion insert bits are ideal for high torque applications. The 1/4″ hex shank fits onto many popular power drills and impact drivers. Additionally, the tapered shock zone absorbs the generated stress on the insert bit to extend bit life. Most importantly, these impact torsion insert bits are CNC machine grounded and designed for a perfect fit with the driven fastener.

Extra hardened, impact rated S2 shock resistant tool steel makes these insert bits more durable than standard insert bits.
