Omega Products ER50 Collet Standard Precision - 10 Micron Run-Out - 38mm - 37.8mm

Omega ER50 Collet — Standard Precision, engineered for dependable, high-accuracy toolholding in ER50 collet chucks. Designed to deliver consistent clamping for round stock with a remarkable 10 micron (0.01 mm) run-out, this collet is built for general purpose machining where precision and repeatability matter most.

• 10 µm run-out: Tight, repeatable gripping minimizes tool deflection, improves surface finish, and extends tool life across routine milling, drilling, and precision operations.
• ER50 compatibility: Specifically sized to pair with ER50 collet chucks, maximizing rigidity and concentricity for a wide range of end mills, drills, and shanks used in CNC machines and manual mills.
• Standard precision construction: Precision-machined steel body with careful grinding and finishing to ensure smooth insertion, uniform clamping force, and reliable performance batch after batch.
• Dimensional reference: Designed with a 38 mm nominal size and a 37.8 mm specification reference, providing a clear fit profile for dependable toolholding in your setup.
• Ideal for everyday machinists: A practical choice for job shops, prototyping, and production environments where consistent grip and repeatability reduce setup time and rework.

Use cases span the spectrum of precision metalworking: secure clamping for end mills and drills during pocketing and contouring, reliable holding when facing or boring, and dependable performance in light to moderate machining tasks. The Omega ER50 Collet Standard Precision is built to resist fatigue under routine machining cycles, delivering stable run-out and predictable results so you can focus on part quality rather than toolholding concerns.

Why choose this ER50 collet? It combines a robust, machined steel body with a proven 10 micron run-out to reduce vibration and chatter, improving cutting efficiency and finish quality. When you need repeatable accuracy across multiple parts or setups, this collet delivers the consistency you expect from a trusted standard in precision toolholding.
