The present invention entails a collet tool for removing a collet from a circumferential retainer and for inserting that collet or another collet into a retainer.

To remove a collet from a retainer, the free end of the collet is inserted into the collet receiving section and the sleeve is pressed onto the collet causing the collet to be radially compressed and lodged within the sleeve and released from its associated retainer. To eject the collet from the sleeve, the plunger is moved into engagement with the collet and the collet is pushed from the sleeve. A collet may be readied for insertion into a retainer by inserting the rear portion of the collet into the collet receiving section. The sleeve is pressed on to the free end of the collet, causing the same to be radially compressed and lodged in the sleeve. To insert a collet into the retainer, the end portion of the collet opposite the free end is inserted into the retainer and the plunger is moved into engagement with the collet and the collet pushed from the slee…
