    • Why doesn’t the Compact Impact Driver/Auto Hammer drive the nail all the way down?

      The HAMMERHEAD Compact Impact Driver/Auto Hammer acts as a swing-less hammer, but still requires some force by the user to drive the nail into the work piece. Apply even and steady pressure as the tool drives the nail and increase the pressure as needed to drive the nail in completely. The Auto Hammer sleeve will retract as the hammer head is pushed down to the work piece, allowing you to drive the nail flush.
