Omega Products ER40 Collet Standard Precision - 10 Micron Run-Out - 2mm - 1.5mm

Omega Products ER40 Collet Standard Precision is engineered for dependable clamping in ER40 collet chucks, delivering consistent grip and concentricity for everyday machining tasks. With a 10 micron run-out, this collet is designed to keep your tooling true and your finishes tight, even when you push your spindle to the limit.

What 10 microns of run-out means in practice: ultra-fine concentricity reduces eccentric loading on the tool, which translates to more consistent hole diameters, smoother milling passes, and cleaner surface finishes. In real-world terms, you’ll see fewer tapering effects on end-milled features and more predictable tool life under routine production conditions. This level of precision is a hallmark of standard precision ER40 collets from trusted toolholding suppliers.

Design and compatibility matter just as much as the run-out spec. These ER40 collets are crafted to DIN 6499 standards and are compatible with a wide range of ER40 collet chucks and toolholders. That means immediate integration with your existing milling or drilling setup, minimal alignment fuss, and reliable performance across different machines and workflows. When you need a proven, drop-in upgrade for precision work, this standard‑precision ER40 collet delivers.

Ideal use cases include micro‑machining, finishing passes, and production drilling where stable gripping force and repeatable runout are critical. Pair these collets with small‑diameter tools for consistent pocketing, pocket finishing, and precise feature creation. The 10 µm run-out specification helps maintain accuracy across multiple passes, reducing the need for rework and supporting tighter tolerances in everyday shop tasks.

Why choose Omega’s ER40 Standard Precision collet over other options? Beyond the tight run-out, these collets are built to deliver dependable clamping performance with broad compatibility and proven, industry-standard precision. If you’re upgrading an existing ER40 setup or building a micro‑manufacturing workflow, this collet helps you achieve repeatable results with less tool deflection and more predictable outcomes.
