Omega Products ER16 Collet Standard Precision - 10 Micron Run-Out - 4.5mm - 3.5mm

Omega ER16 Collet Standard Precision — 10 Micron Run-Out delivers dependable, high-accuracy toolholding for rounds held in an ER16 collet chuck. Built for consistent concentricity, this collet minimizes run-out and maintains true diameter control across each pass, helping you achieve smoother finishes and tighter tolerances in everyday machining tasks.

Why this matters in practice:

• 10 µm run-out tolerance provides precise grip on small-diameter tooling, reducing vibration and chatter that can degrade surface quality.
• Precision-ground, hardened steel construction delivers durable, repeatable clamping performance over many cycles, even in busy shop environments.
• Fits standard ER16 collet chucks, making it a straightforward upgrade for improved accuracy without changing your setup.
• Designed for 3.5 mm to 4.5 mm shanks, enabling secure holding of common micro-end mills, drills, and inserts without tooling changes.
• General-purpose machining ready, ideal for CNC milling, drill presses, engraving, and light contouring where precision and consistency matter most.

In practical terms, this ER16 collet helps you reduce runout-related errors, achieve cleaner pockets and profiles, and rely on repeatable results across multiple parts. It’s a reliable, straightforward upgrade for shops that depend on precise toolholding in compact milling setups, whether you’re producing small features in metal or working with plastics and composites.

Tip for best results: ensure the tool shank and collet seating surfaces are clean and free of debris before tightening, and use the appropriate torque recommended for your ER16 chuck to preserve concentricity over the long term.
