The Omega Products GSK16 Ultra Precision Collet is a purpose-built tool holder for CNC milling, drilling, and high-precision machining. It delivers an exceptionally tight run-out of 5 microns, helping you achieve superior concentricity, tighter tolerances, and better surface finishes. Designed for 12.5mm tooling shanks, this collet provides a reliable, repeatable grip that engineers, machinists, and hobbyists can depend on for demanding applications.

Built with advanced materials and precision manufacturing, it focuses on consistent performance and long-term reliability in everyday workshop conditions.

• 5 μm run-out: Achieves near-perfect concentricity to minimize tool deviation, improving accuracy and surface quality on every pass.
• Secure, repeatable tool holding: Delivers stable clamping and consistent grip, reducing deflection and ensuring predictable results across multiple setups.
• Durable, precision-engineered build (12.5mm tooling): Constructed from high-grade materials with tight tolerances to resist wear and maintain accuracy during tough, real‑world workloads.

With the GSK16 collet, you’ll experience streamlined setups, reduced rework, and more reliable outcomes across precision milling, finishing passes, and high-tolerance projects. The combination of ultra-low run-out, secure gripping performance, and a durable construction translates to fewer interruptions, tighter tolerances, and a smoother workflow from setup to finished part.
