Omega Products ER11 Collet Standard Precision is built to deliver dependable, repeatable toolholding for everyday machining. This ER11 collet is designed to pair seamlessly with a standard ER11 collet chuck, providing tight, concentric gripping on round stock and cutting tools so you can trust your results from the first pass to the last. Why this matters in practice: a 10 micron run-out keeps the tool centered during cutting, reducing chatter and improving surface finish while extending tool life. For both shop-floor production and serious hobby work, that level of precision translates into fewer reworks and more predictable outcomes—time saved and tighter tolerances achieved. Clamping range: 7.8–8 mm, a precise window optimized for small-diameter workpieces and tooling that require tight, repeatable grip. Segmented, precision-ground jaws provide even gripping force around the circumference, minimizing distortion and ensuring consistent pressure where it counts. Hardened steel construction resists wear, preserving accuracy across hundreds of cycles in demanding machining environments. Versatile for general purpose machining—from drilling and milling to pocketing and engraving—on metal, plastics, and other common materials. Designed to fit standard ER11 collet chucks, enabling straightforward integration into existing setups without special adapters. Ideal for machine shops, workshop environments, and dedicated hobbyists who demand reliable, repeatable performance. With this ER11 standard precision collet, you gain a durable, accurate clamp that keeps your diameters true and your workflow steady—allowing you to focus on the cut, not the hold.
