When turning tight-tolerance parts, high-precision collets are critical to maintain tight concentricity, whether the collet is used to hold tooling in a lathe or the material itself. High-precision versions of standard ER collets, like the ETS/ETA-brand, are best for these applications as they provide extreme precision while being easy-to-use and readily-available, like normal ER collets.
