Omega Products ER11 Collet Standard Precision - 10 Micron Run-Out - 3.5mm - 3mm

The Omega ER11 Collet Standard Precision is a compact, high-precision clamping solution designed for ER11 collet chucks. Built for reliability in everyday machining, this collet delivers consistent grip and repeatable results, making it ideal for small-diameter tooling where precision matters.

Key benefits at a glance

• Tenacious accuracy — a tight 10 micron run-out minimizes tool deflection, enhancing dimensional accuracy and surface finish on every pass.
• Optimal clamping range — designed to fit shanks from 3.0 mm to 3.5 mm, providing a precise, secure grip for common small-diameter tools.
• Uniform gripping geometry — a multi-slit design distributes clamping force evenly, reducing run-out hotspots and delivering stable performance under load.
• Versatile compatibility — purpose-built for standard ER11 collet chucks, making it a straightforward upgrade for improved holding power in milling, drilling, and micro-machining tasks.
• Durable, production-ready construction — engineered for repeated clamping cycles in demanding workshop environments without sacrificing precision.

Who benefits most

• Hobbyists and professionals using compact CNC mills, mini-mem milling machines, or drill/tap centers with ER11 chucks.
• Tooling specialists seeking dependable retention for end mills, drills, and small cutting tools within the 3.0–3.5 mm range.

Why this matters for your workflow — lower run-out translates to cleaner cuts, reduced tool wear, and less need for rework. With the Omega ER11 Collet Standard Precision, you can tighten tolerance windows on small-diameter tooling without sacrificing throughput, making it a practical upgrade for precision-focused machining.

Practical usage tips

• Match the collet size to your tool shank (3.0–3.5 mm) for optimal grip and accuracy.
• Before tool insertion, clean both the tool shank and the collet bore to prevent chips from affecting run-out.
• Insert the tool straight and tighten with the appropriate collet wrench to the manufacturer’s recommended torque, then recheck run-out after initial passes.
• Periodically inspect the collet for wear or deformation and replace if you notice increased run-out or tool slippage.
