A portable welding end prep tool that features air-operated clamping which reduces cycle times for highly repetitive end prep milling in fabrication shops is available from ESCO Tool.

The MILLHOG Mongoose Air Clamp welding end prep tool is equipped with an air-operated clamp that attaches to a tube or pipe I.D. and releases from it by simply flipping a toggle switch. Ideally suited for highly repetitive end preps, the pneumatic clamping system reduces operator fatigue and increases throughput by up to 600 percent, claims the firm.

Featuring a self-centering draw rod that rigidly mounts into the tube or pipe I.D., the MILLHOG Mongoose Air Clamp welding end prep tool employs clamp ribs that retract off the mandrel automatically after milling to reduce friction. Designed for tubes and pipe from ⁵⁄₈" I.D. to 3" O.D., this tool can bevel, face, and bore simultaneously and remove membrane.

The tool sells for $3,995 and is available for rent in the continental U.S.
