Omega Products ER25 Collet Standard Precision - 10 Micron Run-Out - 1mm - 0.5mm

Omega ER25 Collet — Standard Precision with 10-Micron Run-Out

Engineered for dependable performance in general purpose machining, the Omega ER25 Collet delivers a precise, repeatable grip on round stock when used with an ER25 collet chuck. The standout feature is an ultra-tight 10 micron run-out, which translates to cleaner holes, straighter slots, and smoother tool travel across milling, drilling, and finishing tasks.

Key benefits that matter in everyday shop work

• 10 micron run-out for exceptional concentricity during rotation, reducing tool deflection and improving surface finish.
• Standard precision design designed to provide a reliable, consistent clamping force in ER25 collet chucks.
• General purpose machining ready — an excellent choice for a wide range of milling and drilling applications where accuracy and repeatability are essential.
• Secure grip on round stock to minimize chatter, improve dimensional accuracy, and extend tool life in routine production tasks.
• Easy integration with existing tooling — compatible with standard ER25 tooling and spindles, helping you upgrade toolholding without changing your setup.

Size notes and compatibility

This ER25 collet is packaged as part of the standard precision family designed for use with ER25 collet chucks. The product title indicates a 1 mm to 0.5 mm size range, making it well-suited for micro-diameter work within the ER25 system. For optimal results, pair this collet with a compatible spindle and clean, burr-free stock to maintain maximum run-out accuracy over time.

Ideal users and practical use cases

• Shop technicians and hobbyists performing precision drilling and small-diameter milling where tight tolerances matter
• Metalworkers who need repeatable results across multiple passes without re-zeroing
• Engraving, micro-machining, and light prototype work where surface quality is a priority

In a crowded market of toolholding options, the Omega ER25 Collet distinguishes itself with a focus on concentric accuracy and dependable performance in everyday machining scenarios. It’s not just about holding a tool—it’s about delivering consistent, high-quality results with minimal setup tweaks.

Upgrade your toolholding with the Omega ER25 Collet and experience steadier cuts, improved surface finishes, and repeatable results that you can rely on for standard precision machining tasks.
