Description

The Omega Products GSK25 Ultra Precision Collet is a high-precision tool holder designed for micro-machining, tight-tolerance milling, and other precision operations. It is built to grip 2.5 mm tooling with exceptional concentricity, delivering a true run-out of just 5 microns. This makes it ideal for engineers, machinists, and hobbyists who demand consistently accurate results from small-diameter tools.

Crafted with advanced materials and precision manufacturing, the GSK25 maintains a reliable, consistent gripping force that minimizes tool play and run-out across repeated cycles. Built for high-precision applications where every micron counts, it helps you achieve repeatable setups and tighter tolerances without sacrificing throughput.

  • 5-Micron Run-Out for True Concentricity: Achieves tight tolerances and smoother surfaces by minimizing tool deviation, reducing rework and improving part quality.
  • 2.5 mm Tooling Compatibility with Secure Grip: Specifically designed to clamp 2.5 mm shanks with a consistent grip, delivering repeatable results and less tool slip during cutting.
  • Rugged, Precision-Machined Construction: Made from high‑grade steel and carefully ground to maintain accuracy and resist wear through heavy use.

This collet supports faster, more reliable setups, reduces tool changes, and delivers dependable performance across demanding machining tasks—helping you hit tighter tolerances, achieve cleaner finishes, and improve overall productivity from start to finish.
