Omega Products' ER40 Collet Ultra Precision clamps round-shank tools in an ER40 collet chuck with exceptional stability. Featuring a 5 micron run-out, they help keep tool paths true for clean finishes in milling, drilling, and finishing tasks.

• 5 Micron Run-Out: Delivers exceptional concentricity for repeatable, high-precision results across cutting operations.
• ER40 Chuck Compatibility: Designed to work with standard ER40 collet chucks for quick installation and secure, accurate tool grip.
• Durable, Precision-Grade Construction: Built to maintain tolerances through frequent tool changes and demanding machining, reducing downtime and rework.

With this ER40 ultra-precision collet, you can clamp round shank tools with confidence, improving concentricity, reducing run-out-induced errors, and delivering cleaner finishes. The low run-out and reliable grip translate into less downtime for rework, faster changeovers, and more predictable results across CNC milling, drilling, or finishing operations. Whether you’re engineering prototypes, producing parts, or tackling hobby projects, these collets help you achieve consistent performance and long tool life.
