In the evolving world of high-precision machining—where multi-task turn-mill centres, high-speed finishing and ultra-tight tolerances dominate—the tool-holder interface becomes a core performance component, not just an accessory. The PSC Tool Holder Series from XiRay is engineered for this reality: it combines the advanced PSC (Polygon Shank Conical) interface standard with shrink-fit clamping, modular flexibility and application-specific design. According to the company’s product overview, their PSC shrink-fit holders “combine the high rigidity of the Polygon Shank Coupling (PSC) system with the precision and clamping strength of shrink fit technology.”
Product Overview
XiRay’s PSC Tool Holder Series includes several sub-lines: “PSC one-piece shank”, “PSC holder for turning-mills series” and “Modular PSC turning holder”. The series is built on the PSC interface (ISO 26623) standard, enabling tool-holders to support both static milling tasks and driven/live-tool turning/milling operations. This unified interface concept helps manufacturers streamline tool-holder inventory while supporting high-precision, high-rigidity cutting.

Shrink-fit clamping & high precision: XiRay emphasises uniform 360° clamping force and minimal run-out for their PSC series—delivering stability even under high-speed, high-precision cutting.
Modular and turning-mill ready: The “PSC holder for turning-mills” range is designed for modern multitask machines: double-side turning, 45° turning, radial/axial holders—all built on the PSC standard.
Industry-targeted application: The PSC series is marketed for automotive, electronics, medical device and precision parts manufacturing—areas requiring high surface quality, fast change-over and accurate tolerances.
Why Choose XiRay’s PSC Tool Holder Series?
For manufacturers upgrading to agile, mixed-mode machining environments—especially those combining turning and milling or consolidating tooling across machine types—XiRay’s PSC series offers key advantages:
For manufacturers upgrading to agile, mixed-mode machining environments—especially those combining turning and milling or consolidating tooling across machine types—XiRay’s PSC series offers key advantages:
One interface to cover both static and driven tooling across turning and milling, reducing holder-type variety.
Superior machining outcomes: increased rigidity and low run-out translate to better surface finish, tighter tolerances and longer tool/spindle life.
Faster set-ups and higher uptime: repeatable mounting with precision design shortens change-over times—valuable in high-mix or flexible production environments.
Application & Best Practice
To maximise performance: ensure your machine spindle or turret interface is compatible with PSC/ISO 26623 tolerances; follow proper induction or clamping protocols for shrink-fit versions; in a turn-mill or multi-task machine environment use the modular PSC turning-mill holders to standardise across static and driven tooling.
