The Oster 655 With Slide-In Tools

Pipe Masters Have had years of service on the toughest proving ground - job and maintenance shops. They have consistently turned out good threads while standing up under the most rigorous conditions. Flat machine ways mounted on a solidly built fabricated steel base are two reasons for the Pipe Master's durability.

Roll-Over Headstock for Pipe Thread Machines

Roll-Over Headstock! Exclusive "Roll-Over" headstock, standard on all Pipe Master machines, allows fast, easy access to the motor compartment. Removing a single pin allows the complete headstock to be pivoted up and back out of the way to expose motor, brushes and switch box for easy maintenance.

The Oster 654 is equipped with special Swing-Over tools for convenient Pipe Threading Operations. The Oster Quad II Swing-Over features an automatic opening system which guarantees the proper length for NPT threads. Also features through die-head oiling.
