A CNC machine collet is a specialized work-holding device designed to securely clamp cutting tools or workpieces during CNC machining operations. Unlike standard chucks, collets provide higher precision and stronger gripping force due to their conical shape and spring-steel structure. They are widely used in milling machines, lathes, drilling centers, and grinding machines, making them a core component of modern precision manufacturing.
