ABSTRACT:
Holder for a threading die. A die holder is provided for threading elongated items of circular cross section, particularly pipe or rod, which can utilize dies of either hexagonal or circular external contour, which can be arranged to reach otherwise awkward places, which can be rotated either by a wrench or by handles and which under certain conditions of use permits a long article such as rod material to pass entirely therethrough. A generally tubular body part has a recess, preferably hexagonal, in one end thereof for the reception of either a hexagonal or a circular die. If a circular die is used, same can be held in position by a set screw. The other end of said body member is externally contoured for receiving a wrench and has an end opening of normally rectangular cross section which is on a common center with the axis of said die. Thus, said die holder can be rotated by a wrench either directly on said last-named end thereof or through an extension inserted into said rectangular opening. There is also provided cross arms which may be threaded or pressed into position radially of said die holder for effecting rotation thereof if preferred. If the die holder is rotated either by a wrench or by said cross arms, same may be used to thread a rod and the rod may then project through said rectangular opening.
