Abstract: A collet construction is described for split sleeve, single angle, outside taper straight bore type collets which provides a more nearly uniform closing action over a range of bore diameters for collet sizes such that the gripping length is less than the full length of the collet. This construction involves locating both the front and rear sets of ties joining the slots within the gripping length of the collet as long as the flexibility requirements allow, and in situations in which such a configuration is impractical due to a resulting excessively stiff collet, a tapered relief on the collet O.D. is provided which creates an even closing rate despite the fact the ties are not all located within the collet gripping length.
