Mongoose MILLHOG

Imperial Range0.625" I.D. – 3.0" O.D.
Metric Range15.9mm I.D. – 76.2mm O.D.

The Mongoose MILLHOG is a torque-free beveling machine for tube and pipe from 0.625" (15.9mm) I.D. to 3.0" (76.2mm) O.D., and at only 2.25" (57.15mm) wide it is ideal for power station boiler tube work and constrained access situations.

The Mongoose MILLHOG is a torque-free beveling machine for tube and pipe from 0.625″ (15.9mm) I.D. to 3.0″ (76.2mm) O.D. and is only 2.25″ (57.15mm) 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 bearings and employs the rigid EscoLock blade locking system, which provides chatter-free performance and produces a thick chip without cutting fluids.

The MG-175 mandrel kit is designed for the Mongoose gear head and allows the tool to fit in tube with 0.625" (15.9mm) I.D. Includes a specific cutterhead that fits the smaller 0.625" mandrel along with the draw rod assembly. Clamping range: 0.625" (15.9mm) I.D. – 0.780" (19.8mm) I.D.

Includes: (1) Mandrel 0.625" (15.9mm) (1) Actuator 0.625" (15.9mm) and draw rod assembly (1) Draw rod stop collar (1) Clamp Rib set G-02A (1) Cutterhead 2.25" (57.2mm) for 0.625" (15.9mm) Mandrel

Wedge Kit — MG-400

The Mongoose wedge kit is used in heavy-wall applications or when the user needs to extend the range of their Mongoose. Hardware easily slides over the existing 3/4" mandrel and includes a draw rod assembly to fit the larger H-series ribs. Clamping range: 1.525" – 2.9" I.D. (38.8mm – 73.7mm I.D.)

Includes: (1) Wedge (1) Draw rod assembly (1) Screw (1) Torque key (4) Clamp Rib sets H-02 through H-05

Air Clamp — G-270

The Air Clamp for the Mongoose 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.

Includes: (1) Air Actuator Clamp System, complete

Membrane Removal Head — See size chart

Cutting head designed to remove the membrane between tubes on a boiler panel. Membrane heads use MRB-8 inserts (8mm carbide bit, same insert as Overlay heads) to remove material. A specific base cutterhead is required for mounting.

Includes: (1) Membrane head (specify size) (3) Mounting screws NOT INCLUDED: Base head (see size chart) Inserts
Tube Size (in) Tube Size (mm) Membrane Head Base Head # of Inserts
1.187" 30.2mm MO-103 MGB-103 4

Overlay Removal Head — See size chart

Cutting head designed to remove the membrane and overlay on boiler panels coated with overlay material. Uses the same 8mm insert as the membrane heads. A specific base head is required for mounting. Slightly smaller circumference than membrane heads forces the head under hard material.
