The overall length of the shank of a mandrel assembly — i.e., the length of a non-inserted mandrel body or the combined length of a mandrel nose insert and mandrel body. This specification does not include the ball assembly and typically varies according to set standards relative to tube diameter. However, overall length may be increased and decreased from the standard to accommodate special considerations involving the reach of the mandrel rod or the collet of a tube-bending machine.

A complete guide to the principles of the 4-Step set-up for tube-bending tools
This is a printable handbook showing how to implement in four standardized steps the “forward mandrel” set-up for rotary-draw tube-bending machines and establish process control over the so-called black art. The procedure is based upon the guiding principle that the tools make the bend and takes advantage of the inserted design of modern mandrel tooling.
