Omega Products ER20 Collet Standard Precision - 10 Micron Run-Out - 15.5mm - 15.3mm

Meet the Omega ER20 Collet – Standard Precision, a reliable choice for precise tool holding in your ER20 collet chuck. Built for general-purpose machining, this collet emphasizes concentricity and repeatable performance with a standout 10 micron run-out, helping you achieve cleaner cuts, tighter tolerances, and smoother finishes across a range of materials.

Designed to clamp round tooling securely, the Omega ER20 collet delivers consistent grip and minimal deflection during high-speed cutting. That means less tool chatter, longer tool life, and steadier feeds and speeds whether you’re milling, drilling, or light finishing tasks on steel, aluminum, or plastics. With its standard precision construction, you get dependable performance without the complexity of higher-tolerance systems.

Why this matters in your workshop:

• 10 micron run-out for exceptional axial accuracy and improved surface finish
• Concentric clamping on round tooling, reducing vibration and ensuring consistent tool engagement
• Broad compatibility with ER20 chucks and a wide range of end mills and boring tools
• Compact, easy-to-change solution that enhances workflow in benchtop CNCs and small milling setups
• Ideal for DIY machinists, hobby shops, and professional shops that value reliability and repeatability

Who benefits most: machinists and hobbyists who demand tight tolerances on small-diameter cutters, drills, and reamers. If your projects include precision pocketing, contouring, or finish passes where run-out can influence part quality, this ER20 collet is a dependable choice to keep your workpiece within spec.

Practical tips for best results: pair the collet with a compatible ER20 chuck, keep the interface clean and free of chips, and perform occasional run-out checks with a test piece to confirm consistent performance after tool changes. Regular inspection helps maintain the 10 micron run-out advantage over time.
