NAMCO N-3 Thread Rolling Head 7/16″ – 7/8″ 1-3/8″ Shank $800

This is a NAMCO N-3 Thread Rolling Head.  It has a capacity of 7/16″ to 7/8″ and the shank is 1-3/8″ diameter.  It has been used and has some wear.  As can be seen in the last photo, one of the bolts needs a washer and a nut.  It works nicely by hand.
