ABSTRACT OF THE DISCLOSURE The present invention entails a collet tool for removing a collet from a circumferential retainer or nose piece and for inserting that collet or another collet into a retainer or nose piece. Specifically, the tool includes an elongated sleeve having a collet receiving section formed about one end and a plunger reciprocally mounted within the opposite end of the sleeve. 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 released from its associated retainer. In the process of compressing the collet the same becomes lodged within the sleeve. To then eject the collet from the sleeve, the plunger is moved into engagement with the collet and the collet is pushed from the sleeve. Then, with the tool being free of any collet, another 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 rear (free end) portion 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 -18- the sleeve. once the collet has been ejected from the sleeve, the same may radially expand and through this expansion the new collet is confined within the retainer.
