The Omega GSK25 Ultra Precision Collet holds 6 mm tooling shanks with exceptional concentricity, delivering a true 5-micron (5 μm) run-out for consistently tight tolerances in milling, drilling, and finishing. Designed for engineers, machinists, and hobbyists alike, it partners with high-precision toolholders to minimize run-out, improve part quality, and reduce rework.

• Ultra-Low Run-Out: Achieves a 5 μm run-out to maximize concentricity, helping you hit precise hole sizes and deliver smooth surface finishes even at higher speeds and feeds.
• Dependable, Consistent Grip: Precision-ground jaws and a robust clamping mechanism provide steady, repeatable grip on 6 mm tooling, reducing tool slip during demanding cuts.
• Durable, Precision-Crafted Build: Made from hardened alloy steel with meticulous manufacturing, designed to maintain accuracy through repeated clamping cycles and long service life.

With true 5 μm run-out and a secure 6 mm tool hold, you gain repeatable results that improve part quality, reduce rework, and streamline workflows. Whether you’re setting up a CNC mill, performing delicate finishing passes, or producing multiple parts, the GSK25 collet helps preserve tolerance, extend tool life, and deliver reliable performance project after project.
