ABSTRACT:
A quick-change tool-holding method and system for securing a tool within a primary tapered recess is disclosed. The tool-holding system includes an adaptor having a tapered exterior that closely approximates interior dimensions of the tapered recess to fit snugly within the tapered recess. The adaptor defines a secondary interior tapered recess and includes an exterior threaded portion about an aperture leading into the secondary tapered recess. A threaded fastener is also provided to include a threaded portion that is cooperable with threads provided adjacent to the primary tapered recess to secure the adaptor therein, as well as an aperture through which at least a portion of the exterior threaded portion of the adaptor extends when the adaptor is secured within the primary tapered recess by the threaded fastener. A collet comprising a plurality of slits formed therein is provided to allow the collet to elastically deform and constrict the tool when placed within an internal passage defined by the collet. An end cap with threads that are cooperable with the exterior threaded portion of the adaptor is included to urge the collet into the secondary tapered recess resulting in a constricting force on the tool within the collet's internal passage.
