Abstract

A portable, power-driven machine for cutting a threaded rod to any required length by forcing a blade punch into a die cavity. The die has a series of semicircular internal threads which extends across the die cavity and which mates with the thread on the threaded rod in order to protect the latter from being ruined by cutting. The internal threads on the die have a depth less than the depth of the thread on the threaded rod, and clearances are provided between the flanks of the die thread flanks and those of the thread on the threaded rod, so that the die contacts the threaded rod only between the roots of the threads on the die and the crests of the thread on the threaded rod, in order to prevent those of the die threads which are located next to the die cavity, from being ruined by the impact of cutting.
