Omega ER50 Collet Standard Precision – 10 Micron Run-Out

Achieve repeatable, high-precision holding in your machining workflow with the Omega ER50 Collet Standard Precision. Designed to pair seamlessly with an ER50 collet chuck, this collet delivers exceptional concentricity and dependable grip for round tooling and workpieces across a range of common milling and drilling operations.

Key benefits that matter in real work

• Ultra-tight run-out for cleaner finishes — a 10 micron run-out minimizes tool deflection and concentricity errors, resulting in truer cuts, smoother finishes, and tighter tolerances on aluminum, steel, and plastics.
• Reliable general-purpose performance — engineered for everyday machining tasks, this ER50 collet maintains consistent clamping force during repeated cycles, reducing setup time and part-to-part variability.
• Durable, precision-ground construction — built to withstand high-speed machining and multiple tool insertions, delivering long service life in professional shops and busy home shops alike.
• Versatile application fit — ideal for CNC milling, manual milling, drilling, reaming, and light threading where secure, concentric gripping of round stock is critical.

Who benefits — machinists, CNC operators, toolmakers, and shop enthusiasts who demand reliable toolholding and predictable performance. If you’re upgrading an ER50 chuck or establishing a dependable baseline for general-purpose machining, this collet helps you hit tighter tolerances and finish with confidence.

Practical guidance for best results — pair with the appropriate ER50 chuck, ensure clean seating surfaces, and follow your machine’s torque specifications for tightening. Regularly verify run-out with a dial indicator to maintain peak accuracy over time.
