VCT 1/2" DR Reversible Hand Held Impact Driver and Impact Screwdriver Bits Set

Features permanently etched left and right directional markings on the front end of the handle. Adjustments can be made by pushing and turning top of the impact screw driver. Just remember "Right-y Tight-y, Left-y Loose-y"! Insert a suitable bit into the bit adapter and set the bit in screw head. Strike the end of the tool handle with a hammer to turn drive 20 degrees in desired direction. To use as a socket wrench, release the bit adapter, then use 1/2-inch impact drive sockets in similar fashion. This tool works without air or electrical components, making it incredibly easy for anyone to use. (Hammer not included.) Always remove any dirt buildup from the screw to prevent damage to the screw head and use protective gear to prevent injury.
