Omega Products ER40 Collet Standard Precision - 10 Micron Run-Out - 5mm - 4mm

Omega ER40 Collet Standard Precision with 10 micron run-out is built for reliable, repeatable holding in your ER40 collet chuck. This high‑precision collet delivers true concentricity for everyday machining tasks, helping you achieve cleaner cuts, tighter tolerances, and longer tool life.

Why this ER40 collet stands out

• 10 µm run-out means less tool deflection, more accurate end mill and drill performance, and superior surface finishes on aluminum, steel, and composites.
• Standard precision design ensures smooth clamping and consistent results across jobs that demand dependable accuracy without the need for specialized tooling.
• Rigid, hardened steel construction provides enduring durability under typical CNC and manual milling conditions, resisting wear that can degrade run-out over time.
• Direct compatibility with ER40 chucks—drop this collet straight into your existing toolholding setup for quick, repeatable tool changes and trustworthy clamping force.

Ideal use cases

This ER40 collet is purpose-built for precision milling, drilling, and finishing where concentricity matters most. Use it with standard shank tooling to maintain strict tolerances on small-diameter end mills, carbide drills, and other round tools. It’s particularly well-suited for benchwork, educational labs, and shop floors where dependable performance and quick changes save time and reduce waste.

Practical guidance for best results

To maximize accuracy, pair this ER40 collet with a compatible drawbar and clean, debris-free tool shanks before clamping. Regularly inspect the collet bore for wear, and rotate tools to even out wear patterns. Store collets in a clean, dry environment to preserve concentricity and clamping effectiveness over the long term.

Choose the Omega ER40 Collet Standard Precision when you need dependable, repeatable performance that keeps tools centered and cuts precise—time after time.
