Description
The RIDGID Model 300 Compact Threading Machine is
an electric motor-driven machine which centers and
chucks pipe, conduit and rod (bolt stock) and rotates it
while threading, cutting and reaming operations are per-
formed. Left-hand or right-hand rotation can be selected
with the FOR/OFF/REV switch. Threading dies are mount-
ed in self-opening or quick-opening die heads. An auto-
matic oiling system is provided to flood the work.
The RIDGID Model 300 Compact Threading Machine can
also be used as a power source for roll grooving equipment.
Designed to attach to the carriage rail of the Threading
Machine, the roll grooving equipment forms standard roll
grooves on a variety of pipe sizes and materials.
