Learn more about Klarna
Description
The Omega GSK25 Ultra Precision Collet is a high-precision tool holder designed for demanding machining work. It delivers exceptional run-out control, achieving just 5 microns of run-out to maximize concentricity and keep cutting tools aligned for tight tolerances.
Sized for a compact 21.5mm form factor, the GSK25 combines advanced materials and refined manufacturing techniques to provide reliable gripping force. This makes it suitable for engineers, machinists, hobbyists, and shop floor technicians who require consistent performance in precision applications.
- Ultra-Low 5-Micron Run-Out: Delivers superior concentricity for repeatable cuts and tight tolerances across jobs.
- Reliable, Consistent Tool Holding: Maintains secure grip on tooling, minimizing slip and deflection during heavy cuts.
- Durable, Precision-Engineered Construction: Built to stand up to demanding workshop use, reducing downtime and extending tool life.
With the Omega GSK25, you’ll experience smoother setups, fewer rework passes, and more predictable results. The combination of precise run-out control and robust gripping power translates to improved part quality, faster production cycles, and lower total operating costs—even in high-volume or high-precision environments.
