Omega Products ER40 Collet Standard Precision - 10 Micron Run-Out - 25mm - 24mm

Omega ER40 Standard Precision Collet — 10 Micron Run-Out, 24–25 mm Range

Meet a dependable workhorse for your ER40 collet chuck setup. This Omega ER40 standard precision collet is engineered to hold round tooling and workpieces with repeatable accuracy across demanding machining tasks. The standout feature is its true 10 micron run-out, delivering tighter concentricity and cleaner finishes on every pass.

Why this matters in practice

• Precise run-out for better tool paths: A 10 µm run-out minimizes eccentricity between the tool shank and spindle, helping prevent chatter, reducing surface waviness, and extending tool life during milling, drilling, and reaming.
• Consistent clamping range: Designed for a 24.0–25.0 mm clamping window, this collet ensures a snug, repeatable grip on tools and shafts sized within that range, ideal for standard machining workflows.
• Optimized for ER40 collet chucks: Built to mate with typical ER40 toolholding systems, enabling straightforward upgrades or replacements without changing your setup paradigm.

Key features at a glance

• Run-out accuracy: 10 microns (0.01 mm) to support precise, concentric cutting.
• Clamping range: 24.0 mm to 25.0 mm, matching common ER40 tooling and shank sizes.
• Intended use: Standard precision collet for general purpose machining, ideal when reliability and repeatability matter most.

What this means for your shop

Whether you’re facing high-precision milling, pocketing, or finishing passes, the Omega ER40 standard collet helps you achieve consistent results without chasing runout-related defects. It’s a practical upgrade for shops that rely on ER40 tooling and want dependable performance without stepping up to ultra-precision variants.

Tips to maximize performance:

• Keep the mating surfaces clean and free of debris to preserve tight run-out.
• Torque to the recommended clamping force for ER40 collets and avoid over-tightening, which can distort the collet and degrade concentricity.
• Use it with properly aligned ER40 chucks and compatible tools within the 24–25 mm range for repeatable results.

For shops prioritizing consistent, economical precision in everyday machining, this Omega ER40 Standard Precision Collet provides reliable clamping, repeatable results, and a clear path to better surface quality without stepping into higher-tolerance tiers.
