Omega Products ER40 Collet Ultra Precision- 5 Micron Run-Out - 9mm - 8mm

Omega Products ER40 Collet Ultra Precision clamps round shank tools in an ER40 collet chuck with exceptional concentricity for ultra-high precision machining. It supports tool shanks in the 8–9 mm range and delivers a guaranteed 5 micron run-out to help you maintain tight tolerances and repeatable finishes.

• 5 Micron Run-Out: Delivers exceptionally close grip to the tool shank, minimizing eccentric movement and enabling tighter tolerances and smoother finishes in every pass.
• 8–9 mm Shank Range: Accommodates common round tool diameters, enabling quick, secure clamping without adapters and reducing setup time.
• Durable, Precision-Ground Construction: Made from high-grade steel with precision grinding to resist wear and maintain accuracy across many clamping cycles.

This ER40 collet is designed to keep your machining workflow steady and efficient. With ultra-low run-out, you’ll see more consistent part quality, fewer reworks, and smoother tool performance, even under demanding cuts. Its rugged construction and straightforward compatibility with standard ER40 chucks help you reduce setup time and downtime while delivering reliable, repeatable results across a wide range of tooling and applications.
