A collet for carrying a high-speed drill which comprises a collar ( ) arranged to enclose a drill shank ( ), an outer rim support ( ) arranged for attachment to a drill, and a clamping mechanism between the collar and the outer rim support ( ). The clamping mechanism is arranged to provide clamping forces between said outer rim support ( ) and said collar so that said collar tightly grips a drill shank ( ), as a consequence of centrifugal forces and of off center sprag effect forces.
