Built for Performance
Designed to prep all schedules of pipe from 3.75” I.D. to 14” O.D., the “Commander” MILLHOG® Model C-314 features a state of the art I.D. clamping system that spreads the contact points of the clamps radially inside the pipe. This minimizes vibration for chatter-free end preps on both thin and heavy wall pipe. To assure stable, smooth rotation of the cutterhead, this rugged tool employs opposed tapered roller bearings that are easy to adjust and never wear out.

Powerful and versatile, torque at the cutting blade for the Model C-314 is achieved with the choice of three motor options suited to fit your application(s). All drives are easily changed and are also interchangeable with the “Dictator.”

Like all MILLHOGS, the “Commander” MILLHOG® Model C-314 is simple to operate and designed for years of trouble free service.
