Collet size or shank diameter is a critical specification because it determines what size tools you can safely and accurately hold in your cnc tool holder. The best collet size for you depends on the diameter of the tools you use most frequently, as well as the type of machining operations you perform. A wide range of sizes, from 1/8" up to 1/2" and more, are available in this category, such as the CO-174 (1/4"), CO-182 (1/2"), and CO-194 (1/8"). This range ensures you can find the perfect fit for your specific tooling, maximizing both safety and performance. There are numerous size options available to suit virtually any standard tool shank.
