PSC achieves this performance by deploying a tapered polygon cone shank and flange surface, which supports a high degree of rigidity. With accuracy in X, Y and Z of ±2 micron, PSC holders provide a high level of repeatability. In addition, a reduced overhang length minimises vibration and runout inaccuracy for a high-quality surface finish, making it suitable for both aerospace and general machining applications.

Connected by a triangular conical structure and cross section, which uses 1/20 taper, the PSC features internal coolant channels and a steel tool holder. More than 130 items are available, including a variety of tool-holder styles, internal tools, interface types and shank sizes.
