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.

Includes

Membrane

Membrane Removal Part #: Dependent on size (see chart)

Cutting head designed to remove the membrane between tubes on a boiler panel. Membrane heads use MRB-8 Inserts, and 8mm crabide bit, to remove material (same insert for overlay heads). A specific base head is required for mounting.

Overlay

Overlay Removal Part #: dependent on size (see chart)

Cutting head designed to remove the membrane and overlay on a boiler panel that has been coated with overlay material. Uses the same 8mm insert as the membrane heads to remove material. A specific base head is required for mounting. Slightly smaller circumference compared to the membrane heads which forces the inserts under hard material.
