The width of a rotary-draw bending clamp die or pressure die; the dimension of such a die from the center of its cavity to its mounting face; the dimension lying in the plane of bend and perpendicular to the cavity and corresponding to the X-axis of the tube-bending machine. Most models of rotary-draw tube-benders have a preferred dimension for reach, but it can vary. This is often the case when clamp and pressure dies must have extended reach in a multi-radius stack of two or three or more die sets so that the cavity faces of these dies can reach the different centerline radiuses of their matching bend dies while having a common location for their mounting faces. See height and length.

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.
