Mongoose Millhog 5/8″ ID to 3″ OD

The Mongoose is ideal for beveling all boiler tube alloys and is only 2.250in wide for accessing single tubes in a boiler tube waterwall. It can also be equipped with a boiler tube membrane removal head that removes membrane from between boiler tubes or a boiler tube overlay removal head that removes membrane as well as overlay, cladding or any other type of protection from the tube o.d

Unlike some beveling tools that require a hammer to release the clamps from the tube i.d. the Mongoose incorporates our patented clamp release mechanism that pushes the clamps down the tapered mandrel when releasing the tool from the tube i.d. This maintains clamp assembly integrity and helps prevent the possibility of them detaching in the tube. Permanently attached wrenches provide all operational needs and support maximize efficiency.
