The eccentric bushings are designed for use with 25mm (.984″) and 32mm (1.260″) tool holders in lathes that do not have a Y axis. The bushing, manufactured from tool steel, hardened and ground, enables symmetry corrections within a range of +Y 0.5mm (.020 inch) to –Y 0.5mm (.020 inch ). The eccentric bushings can accommodate tool holders with either 25mm or 32mm shanks and are available in various diameters, allowing the tooling system to be used in a wide variety of machines. Shorter VDI style eccentric bushings are also available.
