Omega Products ER40 Collet Standard Precision - 10 Micron Run-Out - 10mm - 9mm

Engineered for dependable precision in metalworking, Omega’s ER40 Collet Standard Precision delivers consistent clamping force while minimizing run-out. Designed to fit standard ER40 collet chucks, this collet is ideal for machinists who demand accuracy across CNC milling, drilling, and reaming tasks.

Key advantages

• 10 micron run-out ensures concentric engagement between tool and workpiece, reducing eccentric milling and improving surface finish.
• Precise internal gripping for round stock in an ER40 chuck—helps maintain tool alignment under heavy cuts.
• Rugged, hardened steel construction resists wear and maintains tight tolerances over time.
• Optimized for 9–10 mm round stock to enable reliable tool changes and predictable machining results.
• Easy to clean and maintain, with a smooth outer profile that resists debris buildup in busy shop environments.

Whether you're upgrading a home shop CNC or equipping a professional workshop, this standard precision ER40 collet is built to deliver repeatable performance. Use it for drilling, milling, pocketing, and light finishing where tight tolerances and smooth operation matter most. The 10 micron run-out spec translates to longer tool life and fewer rework passes, saving you time and material costs.
