Omega Products ER20 Collet Ultra Precision - 5 Micron Run-Out - 1mm - 0.5mm

Omega Products ER20 Collet Ultra Precision is a high-accuracy toolholding accessory designed to clamp round shank tooling within an ER20 collet chuck. It is ideal for machinists, engineers, tradespeople, and hobbyists who demand repeatable accuracy in milling, drilling, and precision machining tasks.

Featuring an ultra-tight run-out specification of 5 microns, this collet helps minimize run-out-induced errors, delivering cleaner cuts, tighter tolerances, and superior surface finishes even at higher speeds.

• Ultra-tight 5 μm run-out: Keeps cutting tools true through every pass for tighter tolerances, smoother finishes, and less rework.
• ER20-compatible clamping: Specifically designed to securely grip standard round shank tools in ER20 chucks, ensuring repeatable alignment across tool changes.
• Durable, reliable construction: Built to withstand frequent setup and tool changes while maintaining alignment and consistent performance over time.

Using this collet translates to more predictable tool performance, faster setup, and fewer rework cycles. The tight 5 μm run-out supports precise diameters and smooth surface finishes, making it a dependable choice for both high-precision prototyping and sustained production runs.
