Abstract

A pneumatic nail puller tool for use with a standard needle scaler actuator. A needle scaler typically actuates a chipping hammer installed by means of a chuck. The nail puller tool is so sized and configured as to replace the chipping hammer and lock into its chuck. The nail puller, so installed, is useful in quickly removing nails from a work piece, even where a nail head is buried in the work piece. The nail puller includes a central shaft having a shank having flats and a detent seat for locking into the needle scaler chuck at one end and a nail removing claw at the opposing end. The claw is angled relative to the shaft to provide a lever point to assist in extracting the nail. The claw has sharp entrance points for digging into the work piece to grip an embedded nail head.
