1. Precision workmanship Fine craftsmanship delivers the right elasticity and precision, helping tools grip consistently and reducing runout during machining. improves tool stability and cutting accuracy in demanding operations. 2. material Made from 65Mn spring steel, providing stable performance and durable clamping over repeated use. Designed to resist deformation under typical collet loading, aiding repeatable results. 3. Secure packaging Each collet is housed in its own protective container with a label for easy identification and safe storage. Reduces risk of damage and loss, keeping components organized in the workspace. 4. Easy to use Collets must be placed into the collet chuck nut before inserting into the collet chuck, ensuring proper seating and secure clamping. Simple setup supports quick and reliable tool changes in busy workflows. 23 use scenarios CNC milling or routing: clamp end mills or tool shanks with stable grip to minimize runout and improve surface finish. Drill press operations: securely hold drill bits for accurate, straight drilling with reduced vibration. General workshop tool changes: organized packaging and straightforward assembly enable fast, repeatable tool changes in metalworking or woodworking tasks.
