Learn more about Klarna
The Omega Products GSK10 Ultra Precision Collet is a high-precision tool holder designed for CNC milling, turning, and other precision machining tasks. It grips 4 mm tooling with exceptional concentricity, delivering accurate, repeatable results across production runs.
With an ultra-tight 5 micron run-out, this collet minimizes tool run-out and deflection, helping you achieve perfect circles, cleaner holes, and improved surface finish. Crafted from durable materials and manufactured to tight tolerances, the GSK10 provides reliable, consistent gripping force that keeps tooling secure under load.
- 5 µm run-out for near-perfect concentricity: Delivers precise alignment and consistent hole sizes, improving dimensional control and surface finish across parts.
- Secure, uniform gripping: Applies even clamping force along the tool shank to reduce slip and tool wobble during high-feed operations.
- 4 mm tooling compatibility with durable construction: Designed specifically for 4 mm tools, with precision-ground surfaces and robust materials to resist wear and maintain accuracy over time.
Choosing the GSK10 means reliable performance, less rework, and smoother workflows. The true concentricity and strong grip translate into tighter tolerances, higher part quality, longer tool life, and less downtime for adjustments. It’s a dependable choice for engineers, machinists, and hobbyists who demand repeatable results from every cut.
