The Omega ER25 Collet Set Ultra Precision is a complete collection of ER25 collets designed for high-accuracy clamping in milling, drilling, and precision machining. This 15-piece set covers a wide range of common tool shanks, enabling precise performance across multiple jobs without swapping to different kits.

This set spans from 2 mm to 16 mm and features a stated 5 micron run-out, providing reliable grip and consistent results for tight tolerances and clean finishes.

• Wide size range (2–16 mm) in one set: Includes 15 precision ER25 collets from 2 mm to 16 mm, allowing quick changes for different tools and jobs without swapping sets, reducing downtime between tasks.
• Ultra-precise 5 μm run-out: Delivers concentric, repeatable holding to improve accuracy, surface finish, and tolerance control across operations.
• Durable storage case with foam protection: Secure, organized storage keeps each collet in place, protects from damage during transport, and makes it easy to find the right size at a glance.

With this set, you gain flexibility and confidence in your work. The broad size range covers most standard milling and drilling tasks, while the 5 μm run-out helps you achieve cleaner finishes and more consistent results, reducing rework and waste. The organized case speeds up setup, lowers downtime, and protects your investment in precision tooling.
