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 is available from ESCO Tool of Holliston, Massachusetts.

The Esco PrepZilla MILLHOG® I.D. Clamping End Prep Tool is offered with a wide 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 covers the entire range of the tool.

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

The Esco Prepzilla MILLHOG® I.D. clamping End Prep Tool is available for sale and rent.
