Omega Products ER40 Collet Standard Precision with 10 Micron Run-Out is built for machinists who demand dependable concentricity in every operation. Designed to work seamlessly with ER40 collet chucks, this collet delivers consistent clamping force and maximum tool stability for general purpose machining—from precise milling to clean drilling and accurate engraving. The standout feature is a tight 10 micron run-out, translating to truer tool paths, smoother finishes, and longer tool life in everyday shop tasks.

Why this ER40 Collet Makes a Difference
- Exceptional run-out control: 10 μm run-out minimizes eccentricity, improving concentricity and repeatability across multiple parts and operations.
- Reliable ER40 compatibility: Precisely engineered to fit standard ER40 collet chucks, ensuring secure grip on round tooling and workpieces.
- Versatile for general machining: A dependable choice for everyday milling, drilling, tapping, and light finishing tasks where consistent performance matters.
- Durable, precision-ground construction: Hardened steel with smooth mating surfaces resists wear and maintains accuracy under typical shop conditions.
- User-friendly setup: Drops into your ER40 chuck and tightens with a standard nut, enabling quick changes and minimal downtime.
Ideal Use Scenarios
perfect for shops and hobbyists who run a mix of materials—aluminum, steel, and engineered plastics—where repeatable results are essential. Use it for precise pocketing and contour milling, accurate drilling where run-out can affect hole location, and engraving where clean, centered tooling output matters.
Practical Tips for Optimal Performance
- Pair the ER40 collet with well-balanced tooling to preserve the low run-out performance.
- Regularly clean the collet and chuck interface to sustain precision and prolong service life.
- Torque the nut to the manufacturer’s recommended specification to maintain concentric grip without damaging tooling.
- Store in a clean, dry environment to prevent corrosion and keep mating surfaces free of chips and debris.
Whether you’re outfitting a CNC milling setup, a benchtop machining station, or a production line requiring dependable, repeatable clamping, the Omega ER40 Collet Standard Precision with 10 Micron Run-Out delivers the accuracy you rely on—every cut, every part, every day.
