Either the nose insert of an inserted mandrel body or the nose portion of a non-inserted mandrel body, both function in the same manner as the “working” end of the mandrel body. It is positioned at the point of bend to control the flow of material and so takes the brunt of the wear in a mandrel assembly.

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.
