The double-cone clamping collet type 416E / EDA300 with a metric bore has a clamping range that varies from 1,5 mm to 6 mm. This range indicates the collet's ability to clamp tools with diameters within these values, ensuring a secure and precise grip at all times. Thanks to this relatively wide clamping range, the collet can be used to fasten a variety of small-sized tools or components, making it particularly versatile in high-precision machining operations on CNC machines or in other industrial contexts that require high accuracy and stability. The range from 1,5 mm to 6 mm allows for handling various types of tools without the need for frequent collet changes, thus optimizing processing times and increasing operational efficiency. This makes it ideal for applications where quick tool changes are necessary or for operations requiring high flexibility, while still maintaining maximum precision and reliability in clamping.

The main function of double-cone clamping collets is to offer secure and stable clamping while maintaining high precision during workpiece machining. The 416E collet is used in various industrial sectors, including manufacturing, aerospace, automotive, and precision instrumentation production. In manufacturing, for example, it is employed on CNC machines for the machining of metallic and plastic materials, ensuring high dimensional accuracy. In the aerospace sector, where very tight tolerances are required, the collet is essential for the production of complex and critical components. It also finds widespread use in the automotive sector, especially in the production of parts such as crankshafts and gears, where precise and stable clamping is necessary. Finally, in precision instrumentation, the collet proves indispensable for working on delicate and small components, where the risk of damaging the workpiece during clamping must be minimized.
