Collets

A subcategory of chucks, collets incorporate a tapered outer sleeve and an inner cylindrical surface that fits around a tool or workpiece. Collets are typically divided into woodworking and metalworking uses. In woodworking, collets are often used to hold cutting bits in routers, drill presses and other machinery. In metalworking, collets are typically used for holding round bars or tools, but can also be found in hexagonal, square, and custom-shaped configurations.
