Esco 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.
Esco Mongoose Millhog Features
- Narrow body 2.25″ (27.15mm)
- Lightweight and torque-free
- Interchangeable pneumatic, electric and battery motor options
- Patented clamp system, allows the clamps to release from a tube as easily as they tighten
- Permanently attached wrenches
- Bevel, face and bore simultaneously
- Rugged dual-opposed tapered roller bearings support gear drive for non-stop operation
- EscoLock blade holding system reduces vibration and maximizes the number of preps per blade

WEDGE KIT PART #: MG-400
The Mongoose wedge kit is used in applications with heavy wall or when the user needs to extend the range of their Mongoose. Hardware easily slides over the existing ¾” mandrel and comes with a draw rod assembly to fit the bigger H-series ribs. Clamping range of the wedge kit is 1.525″ I.D. – 2.9″ I.D. (38.8mm I.D. – 73.7mm I.D.)

(1) Torque Key
(4) Clamp Rib sets H-02 – H-05


AIR CLAMP PART #: G-270
Air Clamp for the Ground rigidly clamps the tool to the pipe using an air clamp to pull the draw rod instead of the manual clamp wrench. With the flip of a switch, the tool can be clamped or released for high production and reduced cycle times.
This accessory is only available with the pneumatic motor.
Includes
(1) Air Actuator Clamp System Complete
RIGHT ANGLE DRIVE PART #: G-290
When space is not a luxury, the Groundhog can be fitted with the Right Angle Drive so that the motors can be mounted to either side, or up/down. Kike all of our tools, the Right Angle Drive, is constructed out of precision machined components and is easy to assemble with all three motor options.
Includes
- Right Angle Drive Complete
(4) Mounting Screws
MEMBRANE REMOVAL PART #: DEPENDENT ON SIZE (SEE SIZE CHART)
Cutting head designed to remove the membrane between tubes on a boiler panel.
Membrane heads use MRB-8 Inserts, an 8mm carbide bit, to remove material (same insert for Overlay heads).
A specific base cutter head is required for mounting.
Includes
(1) Membrane Head (specify size)
(3) Mounting Screws
DOES NOT INCLUDE
Base Head
