Omega Products ER40 Collet Standard Precision - 10 Micron Run-Out - 12mm - 11mm

Omega ER40 Collet Standard Precision — engineered for dependable grip and true run-out control in everyday machining. Designed to pair with an ER40 collet chuck, this collet delivers consistent concentricity from first cut to final pass, so your round tooling and workpieces stay true through milling, drilling, and finishing operations.

• Ultra-low run-out: 10 micron run-out specification minimizes tool deflection and eccentricity, helping you achieve cleaner surfaces and tighter tolerances on every part.
• ER40 compatibility: Standard-precision design built to clamp securely in ER40 collet chucks, enabling reliable performance with a wide range of round tooling and stock.
• Even gripping action: The segmented, evenly spaced slotted body distributes clamping pressure around the workpiece, reducing distortion and improving repeatability.
• General purpose machining ready: Ideal for routine CNC milling, light drilling, and other precision tasks where dependable concentricity matters.
• Durable, repeatable performance: Precision-ground surfaces and tight tolerances support consistent grip and long-term stability in busy shop environments.

Who should consider this ER40 collet? machinists, hobbyists, and shop technicians who need a reliable, low-run-out solution for round tooling and workpieces. If you’re chasing tighter tolerances, smoother finishes, and repeatable results across multiple jobs, this standard precision ER40 collet is designed to deliver.

Usage notes: insert the collet into your ER40 chuck, select the appropriate fitting tooling, and tighten securely to ensure maximum gripping force and concentricity. For best results, keep tooling clean and properly aligned, and match speeds and feeds to the material and operation at hand.
