A collet set is a vital machine tool for a range of applications. Collets are precision clamping devices, used in a chuck to securely hold a tool or workpiece for accurate machining. They’re the link between the machine and the bit that’s needed to carry out the application. These allow the bit or tool to be swapped, so that one machine can perform multiple jobs! Collets use an expanding sleeve or spring steel with a cylindrical inner surface and a conical outer surface. The tool or workpiece fits snugly against the inner surface and the outer surface fits into the machine. This is tightened down with an external nut to contract the inner surface around the tool or workpiece for an even and secure pressure. Whether you’re using a CNC Milling machine, CNC router machine Lathe or other piece of equipment, having the right collet set that includes the perfect sizes for each application is essential for a flawless finish.
