MILLHOG Boiler Tube Beveling & End Prep

Explore the Esco Tool Millhog brand of boiler tube end prep machines. These tried and true milling motors have been the boiler industry standard for over 60 years. Made in the U.S.A., these machines feature Esco's unique dual-opposed tapered roller bearing design which allows them to endure the toughest boiler applications.

GroundHog

0.5" ID - 2.25" OD

The Ground MILLHOG is a right angle, I.D. clamping beveling machine that is only 1.5in (38.1mm) wide and fits between boiler water wall tubes for beveling a single tube and other boiler tube applications with restricted access. The Ground MILLHOG is made of high quality treated materials for durability. Proprietary bearings support heavy duty gears for smooth operation on the toughest applications. Patented push-pull clamp and release system with permanently attached wrenches eliminate the possibility of loose parts separating from the tool. This high performance machine utilizes the EscoLock wedge style blade lock system and TiN coated blades for chatter-free beveling.

Millhog Boiler Tube Beveler

Mongoose

0.625" ID - 3" OD

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.

Millhog Boiler Tube Beveler

Tube Weasel

0.75" ID - 3" OD

The boilermaker proven Tube Weasel MILLHOG performs precision bevels for accurate weld fit-up and fits a 2.75" (69.9mm) wide opening. Extremely durable, it features a right angle gear drive system which incorporates dual opposed tapered roller bearings. This compact tube beveling tool can be powered by pneumatic, electric or battery motors that are easily interchanged and equally powerful. The Tube Weasel MILLHOG uses the EscoLock cutter blade locking system that securely holds the cutter blade in the cutterhead. Cutter blades have a radical chip breaker that directs the chip away from the tubes surface and minimizes heat build-up.

C-Hog

0.5" ID - 3" OD

The C-Hog 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 light weight and compact. Highly engineered, it incorporates state of the art materials and heat treated components.

FIN MILLHOG

1.25" ID - 2.5" OD

The Fin MILLHOG tube fin removal machine clamps to the tube I.D. and features a patented cutter blade which separates fin from tube O.D. Forget about chipping hammers and grinders! This machine removes 4" / 101.6mm of fin from a tube O.D. in under 4 seconds. Once the tool is attached to the tube I.D. and the power is activated, the operator advances the rotating cutter and engages the spirally wound fin until the desired amount of fin is removed. The quick action of the rack and pinion feed allows the operator to disengage the feed and clear separated fin from the cutter quickly.

Splitframe Clamshells

Splitframe Clamshells for Cold Cutting & Beveling Pipe

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.
