The Omega Products ER11 Imperial Collet is a precision tool designed for imperial-sized cutting tools used in milling, drilling, and CNC work. With a tight 10-micron run-out, it delivers repeatable alignment and minimal deflection, helping you achieve clean, accurate results when paired with standard ER11 collet chucks. 10-Micron Run-Out Precision: Delivers extremely tight tool alignment, reducing eccentricity and improving part accuracy across milling, drilling, and engraving tasks. Imperial-Size Compatibility with ER11 Chucks: Designed for imperial tooling and ER11 chucks, providing a secure grip that minimizes tool deflection and increases process stability. Durable, Precision-Engineered Construction: Built to withstand frequent clamping and high-torque machining, delivering consistent performance and long service life. This collet helps you hold imperial tools with confidence, boosting workflow efficiency by reducing misalignment and rework. The precise run-out and secure grip translate into smoother finishes, tighter tolerances, fewer tool changes, and reliable performance across demanding applications—from everyday project work to precision manufacturing. When used with a compatible ER11 chuck, it supports fast, repeatable tool changes and consistent results every time.
