Omega Products ER16 Collet Standard Precision - 10 Micron Run-Out - 9mm - 8mm

Omega ER16 Collet – Standard Precision, 10 μm Run-Out (8–9 mm)

Designed for reliable, repeatable toolholding in ER16 collet chucks, this standard-precision collet delivers consistently tight concentricity for general machining tasks. With a measured run-out of just 10 microns, you’ll notice improved accuracy on every cut, smoother toolpaths, and cleaner finishes compared with looser setups. 8–9 mm tool shanks fit securely, making it a practical choice for common end mills and tooling in routine production or prototyping.

Key specifications and benefits

• Clamp range: 8–9 mm tool shanks, aligning with the most commonly used small-diameter tooling for precise milling and drilling tasks.
• Run-out precision: 10 μm (0.01 mm) run-out, supporting tighter tolerances and improved surface quality in aluminum, brass, and steel workpieces.
• Standard precision design: Optimized for dependable performance in everyday machining, offering consistent gripping force and concentricity across dozens or hundreds of cycles.
• ER16 compatibility: Built to pair with ER16 collet chucks, a widely adopted system for rigid, accurate toolholding in CNC machines and milling centers.
• Durable construction: Manufactured from robust steel with precise jaw geometry to resist wear and maintain accuracy under busy shop conditions.

Why this level of precision matters: even small run-out translates into minor deviations that compound through a cut, affecting bore diameters, pocket depths, and surface finish. The Omega ER16 standard-precision collet with 10 μm run-out helps you achieve repeatable results, reduce tool wear from wobble, and maintain tighter tolerances across batches. This is especially valuable on small-diameter end mills and when finishing passes are critical to the final part quality.

Use cases and practical tips

• Ideal for CNC milling, drilling, pocketing, and light finishing tasks where concentricity directly influences accuracy and surface finish.
• Pair with a matched ER16 collet chuck and a clean shank to minimize misalignment. Always clean both the collet and tool shank before tightening.
• Use the proper collet wrench and avoid over-tightening to prevent collet deformation, which can compromise run-out performance.
• Run a quick test cut after assembly to verify concentricity and surface finish, especially when switching to a new batch of tooling.

Who it’s for: hobbyists and professionals who rely on consistent toolholding for accurate milling, engraving, and precision drilling. If you routinely work with 8–9 mm tooling and value low run-out for finish quality and dimensional accuracy, this ER16 standard-precision collet is a dependable choice.
