The Tube Weasel Battery MILLHOG® from Esco Tool is a right-angle-drive, ID-clamping welding end prep tool that employs a wedge-style blade-locking system and TiN-coated cutter blades to perform ready-to-weld end preps without cutting oils. Available with a rechargeable, 18-V lithium-ion battery pack, the tool is suitable for use anywhere air or electricity is unavailable.
Featuring three clamps that fully contact the mandrel and expand inside the tube, the unit mills tube and pipe from 0.75 to 3 in. OD and requires a 3-in. radial clearance for boiler tube panel repairs. The battery is rechargeable using 120/220 V and can be retrofit with existing pneumatic versions of the tool.
