The ESCO Mongoose MILLHOG® is a self-centering right angle drive I.D. clamping air-powered end prep tool for boiler tubes ranging from 3/4” I.D. to 3” O.D. and is only 2-1/4” W to fit a “Dutchman.” Featuring a robust gear drive with dual tapered roller bearings, it has a standard 3/4 HP motor or an optional 1.25 HP motor for end prepping stainless steel and other highly alloyed tubes with overlays, and doesn’t need cutting oils.
Providing chatter-free operation, the ESCO Mongoose MILLHOG® utilizes the EscoLock™ rigid blade lock system and T-15 tool steel TiN coated cutter blades with a radical chip breaker that directs the chip away from the tube and minimizes heat generation. Wrenches are permanently attached and a patented push-pull release mechanism pushes the clamps off the mandrel.
The ESCO Mongoose MILLHOG® is priced from $4,495.00 and is available for rental in the continental U.S.A. for $168.00 per week.
