The Omega ER50 Collet Standard Precision - 10 Micron Run-Out - 16mm - 14mm is engineered for machinists who demand repeatable accuracy in every cut. When paired with an ER50 collet chuck, this collet clamps round stock and tooling with astonishing concentricity, keeping run-out to a tight 10 microns for consistently precise results across projects.

Why this ER50 collet stands out

• Ultra-low run-out: a guaranteed 10 micron run-out helps you achieve true, concentric machining, reducing chatter and improving surface finish.
• ER50 compatibility: specifically designed to work with standard ER50 collet chucks, delivering reliable grip and repeatable clamping every time.
• 14–16 mm clamping range: tailored for tools and workpieces in this size window, offering versatile, drop-in use for common milling and drilling tasks.
• Durable, precise construction: machined to tight tolerances from robust steel, delivering long-lasting performance under demanding cutting conditions.
• Consistent concentricity at speed: balanced and engineered to minimize vibration, helping you achieve cleaner finishes and tighter tolerances.

Ideal use cases

Whether you’re performing precision milling, drilling, or reaming operations, this ER50 collet keeps your tooling true. It’s especially valuable for aluminum fixtures, steel trial runs, and any project where concentricity directly influences accuracy and finish quality. If your workflow involves frequent tool changes or high-speed machining, the 10 micron run-out ensures you won’t sacrifice precision during quick setups or rapid cycling.

Practical guidance and advantages

• Use with a calibrated dial indicator to periodically verify run-out and ensure ongoing accuracy on high-speed spindles.
• Keep the collet bore clean and free of debris; a light, compatible lubricant on the chuck interface can help maintain smooth clamping action.
• Pair with compatible ER50 tooling to maximize grip and minimize run-out-induced wear on both collet and tool shank.
