What Is a PSC Turning Holder?
A PSC Turning Holder leverages the Polygonal Shank Coupling (PSC) interface — a high‑precision toolholder connection standardized under ISO tooling standards. Unlike traditional holders that rely mainly on a simple tapered fit, PSC holders combine a polygonal taper with flange face contact to create a rigid, self‑centering connection between the toolholder and machine spindle.
This interface delivers:
Greater rigidity and torsional strength
Improved vibration resistance
Higher torque transmission
Repeatable accuracy after every tool change
The Modular PSC Turning Holder from Xiray Tools takes these benefits further by offering a modular head system, allowing you to switch between grooving, profiling, threading, and other turning tasks — all using the same base holder.

What Is a PSC Tool Holder?

A PSC (Polygonal Shank Coupling) Tool Holder is a high‑performance tool holding interface standardized under ISO 26623. Unlike traditional taper‑only systems (such as CAT, BT, or HSK), a PSC holder engages both the polygonal taper and the flange face to secure the tool in the machine spindle.
This dual‑contact surface results in:
Higher rigidity and reduced vibration
Improved torque transmission
Micron‑level repeatability
Faster modular tool changeovers
Better performance under heavy cutting loads
Because of its performance advantages, PSC tooling is increasingly discussed in machining forums and search trends related to repeatability, tool life, and rigid holding systems.
