Dasco Pro 5/32" Point x 1-1/2" x 5 1/2" Pin Punch, made of heat-treated, high carbon American steel, is machined to exacting standards for a wide variety of uses in driving and removing pins and keys. It is used after initial removal by a machine punch or starter. To prevent damage to the side walls containing the pin, use a pin punch one size smaller than the pin being driven.
