In today’s machining environment—where multi-axis turn-mill centres, high-speed finishing, and ultra-tight tolerances dominate—the tool-holder interface has evolved into a strategic performance factor rather than just a support element. The PSC Tool Holder series from XiRay responds precisely to these demands by combining the PSC (Polygon Shank Conical) interface standard with high-rigidity construction and precision clamping technologies. According to XiRay’s product overview, the PSC series is described as “advanced tool holding solutions designed to combine the high rigidity of the Polygon Shank Coupling (PSC) system with the precision and clamping strength of shrink fit technology.”

Product Overview
The PSC Tool Holder supports the PSC interface (ISO 26623 standard) and is offered in multiple configurations—one-piece shank variants, holding systems for turning-milling machines (“PSC holder for turning-mills series”), and modular PSC turning holders. The design enables manufacturers to adopt a unified tool-holding platform across static milling, driven/live tooling, and turning operations. This consolidates inventory, simplifies tool-holder strategy, and enhances flexibility in modern multi-task machining environments.
Key Features & Benefits
PSC Interface Compatibility: The polygonal shank plus conical coupling delivers large contact surfaces and high torsional rigidity, which supports repeatable, precise tool changes and stable performance under load.
Shrink-Fit Clamping & Accuracy: The series integrates shrink-fit technology, offering uniform 360° clamping force, minimal run-out and high-speed capability—critical for high-speed finishing and precision operations. According to the product page, run-out accuracy is down to ≤ 3 µm in some models.
Versatile Multi-Operation Use: The “Turning-Mills” variants accommodate double-side turning, 45° angle holders, radial and axial configurations—enabling one interface family to work across milling and turning machines.
Industry-Focused Application: Mentioned target sectors include automotive, electronics, medical devices and precision parts manufacturing—where change-over speed, surface finish, and tool life are paramount.
Why Choose the PSC Tool Holder?
For manufacturers stepping into flexible, high-mix or multi-task machining setups, the PSC Tool Holder offers strategic advantages:
Unified tooling interface: One interface across static and driven tooling, turning and milling—reducing tool-holder type proliferation and simplifying logistics.
Improved machining outcomes: With enhanced rigidity and precise clamping, surface finish improves, tolerances tighten, and tool/spindle life extends.
Faster change-overs and higher utilisation: The repeatability and robustness of the PSC interface support quicker, more consistent tool changes—key for agile manufacturing.
Application & Best Practice
To realise full benefit: ensure your machine spindle/tool-pocket geometry meets PSC/ISO 26623 tolerances; for shrink-fit variants follow correct induction-heating or clamping protocol; in turn-mill or multi-task machine conditions select the modular PSC holders to standardise tooling across both static and driven formats.
