ESCO Tool of Holliston, Mass., has unveiled a heavy-duty, I.D.-clamping, milling-end prep tool that can J-prep bevel, face and bore all pipe alloys in preparation for orbital welding.

The Esco PrepZilla MILLHOG® I.D. Clamping End Prep Tool is offered with a selection of cutting blades, including a J-preparation blade that creates consistent contoured radius and clean neck for orbital welding. Capable of producing thick chips without cutting fluids for fast fit-up and high-integrity welds, it bevels all highly-alloyed pipes and one mandrel with eight sets of clamps that cover the entire range of the tool.

Suited for heavy-wall pipe from 1.575 in. I.D. to 8.625 in. O.D., the robust Esco Prepzilla MILLHOG® I.D. Clamping End Prep Tool features dual opposed tapered roller bearings, direct-drive gears and a ridged blade lock system. TiN coated T-15 tool steel cutter blades with a proprietary chip breaker transfer heat away from the pipe surface. Interchangeable pneumatic, electric and hydraulic motors are offered.
