Oster Bolt & Pipe Threading Dieheads

A key part of any threading machine is the die head and dies. OSTER machines are equipped with either slide-in Oster die heads, swing-over Oster die heads or the X1 rotating Oster die head. All three perform the same accurate pipe and bolt threading, all three offer you the same high quality and long life that the OSTER trademark has guaranteed since 1893.
