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.
