Prepzilla MILLHOG® Pipe Beveling Tool

Prepzilla MILLHOG® Pipe Beveling Tool

The Leader in Pipe Beveling

From the company that developed the first portable end prep tool as part of the Triton Nuclear Submarine program in the 1950s, ESCO Tool Company is the leading innovator of tools for end prep of high pressure, high temperature hard alloy tubing. Their tools provide the highest power-to-weight ratio available with proprietary designs made specifically for work in difficult, confined spaces. ESCO tools are found in the most challenging work environments including oil and gas platforms, refineries and power generation sites.

Prepzilla MILLHOG® – Designed for Rugged Offshore Use

ESCO Tool’s Prepzilla MILLHOG® P-300W Pipe Beveling Tool is the perfect example of their innovative engineered designs. Its combination of a 2-HP pneumatic motor and extreme-duty gear reduction drive delivers operational speed with 1,500 lbs. of cutting torque. Clamp ribs and pads permit work on pipe or tubing in any diameter from 1.575 inch I.D. to 8.625 inch O.D. End prep of any class of pipe or tubing, including difficult alloys such as stainless steel, Super Duplex and P-91, is performed effortlessly at any required angle.


The Prepzilla MILLHOG® bevels, bores and faces hard to machine pipe with features to ensure a perfect cut, operator convenience and unmatched reliability:

• A single mandrel and eight sets of clamps and ribs cover the full range of pipe sizes
• A dual-threaded clamp design ensures operational stability
• End preps can be made with any angle on any wall diameter
• Draw-rod assemblies are self-centering to ensure a perfect cut
• Titanium Nitride coated cutting blades and the EscoLock™ blade lock system reduce cutting heat
• Thick cutting chips eliminate the need for lubricating or cooling fluids
• Long life is guaranteed by dual opposed, tapered roller bearings
• Low RPM and low operator torque means easy handling
• The exhaust directs air away from the operator

In addition to the features above, the Prepzilla MILLHOG® P-300W can be fitted with two cutter blades and an additional tool post to combine preparation steps. The P-300EW is an electric drive model, which provides the same operating features as the P-300W using an 1800-watt pneumatic motor that takes power from 120 or 240 VAC outlets.
