Omega Products ER20 Collet Standard Precision - 10 Micron Run-Out - 4mm - 3mm

Meet the Omega ER20 Collet Standard Precision — a focused clamp that turns your ER20 collet chuck into a reliable workhorse for precise, repeatable toolholding. Built for general machining, this collet delivers a consistently tight grip on small-diameter tools, helping you achieve cleaner finishes and tighter tolerances with every pass.

Why choose the Omega ER20 Collet for your workshop?

• Ten micron run-out (0.01 mm): A Precision you can feel in every cut—minimizing tool deflection and chatter to deliver straighter holes and smoother surfaces.
• ER20 compatibility: Specifically designed to clamp round tooling within an ER20 collet chuck, ensuring dependable fit and repeatable performance across jobs.
• 3–4 mm tooling range: Optimized to securely grip small-diameter shanks, making it ideal for micro-end mills, small drills, and other compact tools used in precise milling, drilling, and engraving tasks.
• Standard precision, reliable results: A practical choice for shops that require consistent performance without over-spec tooling, balancing precision with everyday durability.

Ideal use scenarios

• Milling small-diameter workpieces in aluminum, plastics, and soft metals where precision and surface finish matter.
• Drilling and countersinking tasks that demand stable toolholding to prevent wander and improve hole roundness.
• Engraving and micro-finishing applications where tight run-out translates to crisper detail and cleaner edges.

Who benefits most

• Machining professionals and shop owners who rely on dependable toolholding in ER20 chucks.
• Hobbyists and DIY CNC enthusiasts seeking consistent performance for small-diameter tooling projects.

Practical tips to maximize performance

• Keep tooling clean before clamp-up. Wipe shanks and collet bore to maintain that 0.01 mm run-out target.
• Use the appropriate ER20 collet wrench and tighten gradually in a star pattern to achieve even clamping force without overshoot.
• Pair with compatible ER20 collet chuck for best results; ensure the chuck is clean and in good condition to preserve precision.
• Inspect for wear or deformation after heavy use; replace if the grip or bore shows signs of life loss to maintain accuracy.
