Pipe Beveling Equipment We Offer
SEC supplies industry-proven pipe and tube beveling tools designed for clean cuts, consistent results, and high-performance operation in demanding environments.
Wart Millhog
The Wart Millhog is a portable right angle I.D. clamping pipe and tube beveling machine that features an efficient low maintenance design. Incorporating a gear drive that is fully supported by dual opposed tapered roller bearings and three heavy duty ball bearings. This gives the Wart the backbone to satisfy a wide variety of applications and is a favorite choice among boilermakers and pipe fitters. All components are made of the finest materials and parts subject to wear are heat treated for durability and long use. Sealed construction prevents debris from getting inside the tool, allowing use in any orientation. What’s more the compact design requires a minimum of 2.625″ to fit between tubes in a boiler tube waterwall.

- Lightweight and requires no special training
- Rugged dual-opposed tapered roller bearings support the gear drive for non-stop operation
- EscoLock cutter blade holding system reduces vibration and maximizes the number of preps per blade
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.

Mongoose Millhog
The Mongoose MILLHOG is a torque free beveling machine for tube and pipe from 0.625” (15.9mm) I.D. to 3.0” (76.2 mm) O.D. and is only 2.25” (57.15 mm) wide which makes it ideal for power station boiler tube work and constrained situations with limited access. Featuring a patented push-pull clamp and release mechanism, it allows the clamps to release from a tube as easily as they tighten. Ideal for beveling, facing and boring on a wide range of tube and pipe alloys, the Mongoose has dual opposed tapered roller bearing and employ the rigid EscoLock blade locking system; which provides chatter-free performance and produces a thick chip without cutting fluids.

C-Hog Millhog
The C-Hog Millhog beveling machine securely attaches to the tube O.D. with a huge clamp that minimizes chatter and vibration and is well suited for small-bore tubes because there is no I.D. clamp or mandrel to interfere. The I.D. clearance gained also allows for large, tough I.D. boring blades that increase Cutter Blade endurance. Designed for maximum operator comfort, efficiency, and ease of use, the C-Hog’s attached feed wrench lets the operator comfortably feed the tool as it bevels the tube with minimal fatigue. Constructed to deliver reliable performance on the toughest applications, the C-Hog is a rugged tool that is lightweight and compact. Highly engineered, it incorporates state-of-the-art materials and heat-treated components.
Using the Millhog pipe beveler is easy and efficient and can help operators achieve accurate results on all materials, including stainless steel, alloy steel, and more. The C-Hog’s rapid feed rate saves time and offers a quality bevel that meets the highest standards. Feel free to contact us for more information on the C-Hog Millhog and learn how it can help you get the job done.
- Narrow body 1.75″ (44.45mm)

Tube Rolling Motors
ESCO Tool Tube Rolling Motors and Tube Expanders are used for fabricating and maintaining boilers, heat exchangers, and condensers. Our rolling motors come in a variety of torque options and have capabilities of performing both straight and flared rolls for the most accurate and tightest bond to the tube sheet. Like all of ESCO Tool’s rental equipment, every tool/machine is completely taken apart, scrubbed clean, reassembled and tested after every job it is on. Tube rolling motors are set up on our torque testing unit to assure the highest level of functionality before they make it to your site.
Understanding the material you are working with, its thickness, and its circumference is essential for any boiler tube rolling motors or expanding task. That’s why the team at SEC Industrial Inc provides our customers with the expertise they need to ensure a successful outcome. We understand how important it is for each job to be done right and on time, so we strive to make sure each of our machines works perfectly.

Clamshell Split Frame Tool
For decades, ESCO Tool has manufactured rugged, reliable and simple to operate tube and pipe fabrication equipment known to the industry as MILLHOG®. Years of working closely with end-users, has led us to develop our own line of split frame machines that hold true to our name. The all new COHOG® split frame eliminates the complication associated with traditional OD mounted tube and pipe fabrication machines while setting a new standard for lasting performance.
At the core of the COHOG® is its uniquely built frame. The stationary ring is machined out of 7075 aluminum alloy, the strongest aluminum obtainable, and hard coated for maximum strength and durability. A full complement of precision-tuned eccentric bearings fully support the rotating ring which is machined from a custom steel forging, heat-treated and nickel-plated for long-lasting corrosion and wear resistance. Self-squaring clamp legs quickly align and secure the machine to the pipe making it rigid enough to part and bevel heavy wall pipe, in one operation, without vibration or chatter. COHOGs feature indexable tool slides and trip mechanisms that use a marked locating system to precisely align and quickly attach without shims or guesswork. A variety of blade modules easily attach to the tool slides and can hold conventional high-speed tool steel blades or cutting inserts. Most cutting inserts have multiple cutting edges, are simple to replace, and provide more cuts per blade at a lower cost.
- Rotating and stationary ring design makes the COHOG® extremely rigid for smooth cutting action on any material
- Components are built using the finest materials and hard anodized or nickel plated for superior corrosion resistance
- Sealed construction protects bearings and bearing races from cutting debris
- Indexable tool slides and trip mechanism use a marked locating system to make setup fast, easy and accurate.
- Modular tool slides use conventional tool steel blades or inserts with multiple cutting edges that proved more cuts per blade at a lower cost
- Full range of all tools is achieved with the internal clamp legs and single set of clamp extensions making mounting simple
- Powerful Pneumatic, Hydraulic and Electric motor options
- Available for sale or rent
