The Esco Prepzilla Millhog

The Prepzilla MILLHOG is smooth, quiet and powerful.

It is highly desired for its ability to bevel difficult pipe alloys like super duplex and P-91 quickly and efficiently.

Ruggedly designed for years of trouble free service, the Prepzilla is built with dual opposed tapered roller bearings, heat treated and hardened clamping, cutting and operational components.

It can bevel pipe at any angle without cutting fluid for fast fit-up and enables precise pipe joint welds.
