A portable denailer is a hand-held pneumatically-powered tool. It works by driving out the nail from the point end in pieces of nailed lumber which have been pried apart. The process of denailing (removing large numbers of nails from salvaged lumber) is greatly expedited by using this specialized tool.
A stationary denailer is a machine designed for single-purpose use, e.g. pallet refurbishing.
