1. A clamp die or clamp insert with a cavity shaped to grip on a bend rather than a tangent. This type of clamp is used when a mid-tangent (i.e., a tangent between bends) is too short for a conventional straight-cavity clamp.
2. A clamp die or clamp insert with multiple cavities.

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.
