Modular tool end forming system is designed to use with the standard, integrated and portable power pack. The power pack top mounted tooling modules are available in three sizes to cover tube diameters from 1/8″ to 3″ OD. By use of individual forming and gripping modules, this system can be configured to specific applications. The gripping modules have quick-change collet sets to accept different tube diameters. The forming modules can be easily converted to a number of different standard end forms such as expansion, reduction, flare and bead.
