The Esco Mini Millhog

The Mini MILLHOG is a ruggedly built beveling machine with a spur gear drive train and bevels all tube and pipe alloys to 6.625” O.D.

It’s combination of rpm and torque also make it ideal for tube stub removal and tube overlay and cladding removal.

All clamping components including the draw rod are heat treated and provide the strength to rigidly secure the tool on the inside diameter of the tube or pipe.

The EscoLock cutter blade holding system securely holds the cutters in the tool post and helps reduce chatter and produce a clean, continuous chip on most pipe and tube alloys without cutting fluids.

Easy to operate and maintain, this tool delivers huge performance in a small package and is available with either a pneumatic or electric motor.
