The COMBI Pistol Grip Screwdriver is a versatile multi-purpose tool. It’s a drill, tapper and screwdriver all in one. Just change your front attachment and it is ready to go. The COMBI screwdriver models do not have clutches, they are direct driven tools. This means that either you release the trigger to stop, or the torque builds up to where the motor can no longer rotate. The screwdriver is lightweight, with optimum non-slip grip and handle design for operator comfort. This tool is reliable and will be your friend for a long time ahead.
