The Omega Products GSK25 Ultra Precision Collet is a high-precision spindle accessory designed for CNC milling and turning, offering a 25mm tooling capacity and near-perfect concentricity. Built for engineers, machinists, hobbyists, and maintenance teams, it delivers reliable, micron-level accuracy to keep tools centered and cutting true during every pass.

• 5 µm Run-Out for Superior Concentricity: Delivers exceptionally tight run-out to maintain tool alignment, helping you achieve consistent tolerances and superior surface finishes.
• Reliable, Repeatable Clamping Force: Precision-ground interfaces and balanced design provide consistent gripping across cycles, reducing tool slip and rework.
• Durable, Precision-Grade Construction: Made from high-grade materials with tight manufacturing tolerances to resist wear and maintain accuracy in demanding shop environments.

With the GSK25, you gain faster, more predictable setups, fewer rework passes, and reliably consistent results across jobs. The 5-micron run-out minimizes deflection and tool run-out, while the sturdy build stands up to daily use, helping you improve workflow, shorten cycle times, and deliver high-precision parts with confidence.
