PRO-10 PB is a heavy-duty ID mounted pipe beveller utilizing self-centering expandable mandrels to provide quick and proper alignment to a pipe or a tube prior to machining operations. The beveller is capable of milling the OD bevel, root face and ID counterbore to create a uniform wall thickness around the joint and ensure full weld penetration. Optional accessories extend the possible applications of the PRO-10 PB to include flange facing and oval beveling.
