  • Patent number: 5218749
    Abstract: A handheld punch tool assembly having individual removable punch segments formed of a high strength material capable of being struck repeatedly by a striking instrument, each of the individual punch segments including a substantially flat punch surface on one end thereof structured to engage in abutting relation with a substantially flat corresponding surface to be punched. Each of the individual punch segments have a different transverse dimension than a remainder of the punch segments so as to effectively vary the size of the punch surface. The individual punch segments are removably attachable to one another to form an elongate, multi-punch segment body of variable length. A plurality of various size collar members are each individually structured to be removably fitted about a corresponding one of the punch segments so as to effectively increase the transverse dimension and accordingly, the size of the punch surface of that particular punch segment.

  • Patent number: 5001822
    Abstract: A handheld punch structure having an integrally formed elongated base of one piece construction and formed of a high strength material capable of being struck repeatedly by a striking instrument or used with a hydraulic press structure. The base defines a plurality of integrally formed punch segments thereon wherein successively positioned ones of the punch segments increase in transverse dimension by a predetermined increment successively from one end towards an opposite end and a gripping portion formed thereon to facilitate gripping by the hand of the user.
