Omega Products ER20 Collet Standard Precision - 10 Micron Run-Out - 2mm - 1.5mm

Omega ER20 Collet, Standard Precision is built for micro-machining where consistent grip and concentricity matter. This ER20 collet is specifically sized for tools with a 1.5–2.0 mm shank, making it a reliable choice for small-diameter milling, drilling, and engraving tasks. With a stated 10 micron run-out, it delivers exceptional accuracy when holding delicate tooling and finishing passes that demand tight tolerance control.

Key benefits and how it translates to real-world outcomes:

• Precise run-out at micro-dimensions: 10 microns of run-out minimizes tool wobble, leading to steadier feeds, cleaner cuts, and smoother finishes on small-diameter tools.
• Socket compatibility with ER20 chucks: Designed to snap into standard ER20 collet chucks, enabling quick tool changes without sacrificing accuracy.
• Small-diameter versatility: Optimized for 1.5–2.0 mm shanks, ideal for micro-milling, fine engraving, and precision drilling where every micron counts.
• General-purpose precision for day-to-day machining: Not just for specialists—the standard precision build provides reliable performance across a range of common machining tasks.
• Contributes to repeatable outcomes: Consistent gripping force and concentricity help maintain tolerances across multiple passes and setups.

Practical use scenarios

• Micro-milling tiny features on PCBs or plastic parts where dimensional accuracy matters.
• Engraving fine details with small-diameter end mills, requiring steady tool control.
• Delicate drilling of precise pilot holes using small shank tools, where run-out can impact hole diameter and finish.

Why choose this standard precision ER20 collet? It strikes a balance between dependable everyday performance and the precision needed for small-tool machining. If you work with tools in the 1.5–2.0 mm range and rely on consistent concentricity, this collet delivers the reliable grip and accuracy that your workflow depends on—without the complexity of higher-tolerance variants.

Tips for best results:

• Ensure the ER20 collet chuck interface is clean before seating the tool to preserve accuracy.
• Insert the tool straight and tighten the chuck securely to maximize grip and minimize run-out drift.
• Use appropriate cutting speeds and feeds for small-diameter tools to leverage the collet’s precision.
• Inspect tooling and replace worn or damaged collets to maintain consistent performance over time.
