The Mini MILLHOG is a ruggedly built beveling machine with a spur gear drive train that bevels all tube and pipe alloys to 6.625″ O.D. Its combination of rpm and torque makes it ideal for tube stub removal and tube overlay/cladding removal.
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. Its 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.

| Mandrel Kit (1.25″ / 31.8 mm) – M-240 | The M-240 mandrel kit is designed to fit in the Mini MILLHOG gear head and will allow it to fit in tube or pipe with a 1.25″ (31.8 mm) I.D. This kit works with both Cutterhead options and comes with everything needed to assemble. Clamping range of this mandrel kit is from 1.25″ (31.8 mm) I.D. to 1.925″ (48.9 mm) I.D. |
| 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 (8 mm carbide bit, same insert as Overlay heads) to remove material. A specific base head is required for mounting. |
| 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 8 mm insert as the membrane heads. A specific base head is required for mounting. Slightly smaller circumference than membrane heads forces the inserts under hard material. |
