Esco Tool introduced The C-Hog Millhog O.D. clamping end prep tool, a portable beveling tool for performing end preps on thin-wall tube. The tool evenly distributes holding power to securely mount on the outside of high-purity thin-wall tube and perform chatter-free welding end preps. Maintaining the integrity of the inside of the tube, it can produce any angle of prep including j-preps without needing cutting fluids. Capable of prepping and flat-facing simultaneously, the tool is suited for tube and pipe from 0.50 in. ID to 3.0 in. OD.
