Omega Products ER11 Collet Standard Precision - 10 Micron Run-Out - 2.5mm - 2mm

Omega presents the ER11 Collet Standard Precision, a trusted choice for tight, reliable clamping in your ER11 collet chuck. Engineered for small-diameter tooling, this collet delivers true, repeatable performance with a precise 10 micron run-out. Whether you’re milling, drilling, or performing delicate micro-machining, you’ll achieve cleaner cuts and better tolerances thanks to superior tool seating and concentricity.

• 10 micron run-out minimizes deviation between tool and spindle, translating to crisper holes, tighter diameters, and smoother finishes across passes.
• Size range shown in the title: 2.5mm - 2mm, designed to accommodate small-diameter tools and round stock with dependable grip.
• Standard ER11 compatibility plug-and-play into most ER11 collet chucks for seamless integration into your existing setup.
• General purpose machining ideal for hobbyists and professionals tackling micro-milling, micro-drilling, engraving, and light-duty machining tasks.
• Reliable, repeatable results reduce setup time and calibration needs, letting you focus on accuracy and throughput in busy workshops.

Use cases include precision pocket milling of small features, accurate micro-drilling, and consistent tool seating for intricate engravings. When paired with a stable spindle and compatible ER11 tooling, you’ll notice improved concentricity and a superior surface finish on common materials such as aluminum and brass.

This Omega ER11 Collet is an excellent upgrade for model makers, electronics enclosures, prototype shops, and education labs that demand dependable, repeatable results from small-diameter tooling. It strikes a practical balance between precision and value, helping you achieve higher accuracy without adding complexity to your workflow.

Tips for best results: keep the collet clean of chips and coolant, apply appropriate clamping torque to prevent tool pull-out, and verify run-out with a quick test cut before committing to production passes.
