Description
Meet the Omega ER20 Collet Standard Precision — a dependable, high-precision clamp for round tools in an ER20 collet chuck. Built for consistent performance in everyday machining, this collet delivers clean runs and reliable gripping so you can focus on the cut, not the wobble.
Why this ER20 collet stands out
- 10 micron run-out for tight tolerances and superior concentricity across every pass. Small-diameter work tends to show errors quickly; this collet minimizes run-out to help you achieve smoother finishes and more accurate diameters.
- ER20 compatibility with standard ER20 collet chucks, making it a straightforward upgrade or replacement for existing setups without changing fixtures or tooling routines.
- Designed for small-diameter tooling and micro-machining tasks, efficiently clamping tools in the 1.0–1.5 mm range for precise milling, drilling, and engraving applications.
- Durable, reliable construction built to withstand frequent tightening and high-speed machining, helping you maintain consistent performance project after project.
Ideal uses and real-world applications
Whether you’re refining a new prototype or finishing a production run, this ER20 collet shines in scenarios that demand tight tolerances from tiny tooling. Use it for:
- Micro-milling of jewelry, electronics housings, or precision fixtures where concentricity matters
- Fine-drilling and deburring of small-diameter holes
- Engraving, etching, or slotting on delicate workpieces where run-out can affect depth and width
How it improves your workflow
With a 10 µm run-out specification, you’ll notice reduced tapering and improved finish quality on small-diameter features. The precise grip minimizes tool deflection, enabling higher feed rates without sacrificing accuracy. That translates to less rework, shorter cycle times, and more predictable results for your milling or drilling operations.
