    great tool
    It works great for smaller nuts and bolts. Does not have enough torque for bigger applications. Does not replace air tools. Had to sand down the retention knob to get my existing sockets on and off.

    CPO is a good company
    This tool has absolutely no power at all. It is useless to me. My 18v dewalt 1/4 impact driver has more. Totally dissatisfied with this purchase

    New Vs. Reconditioned

    What's the difference between New and Factory-Reconditioned?

    Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
    • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
    • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
    • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 60 days.
