The Bosch GDS 30 Professional Impact Wrench is a powerful tool for large screwdriving applications. It is the ideal solution to working with screw joints on trucks, construction machinery, in commercial vehicle construction, in petrochemical or other heavy industries. The auxiliary handle with packing pad can be fitted in two difference positions for easy handling no matter the situation; there is even a hanging hook for attaching the tool to a balancer. The V-groove impact mechanism has low recoil torque for improved tool life whilst still offering high impact performance with low weight. There are both forward and reverse rotation functions for tightening and loosening.
