Abstract
A drill/driver chuck mechanism has a cylindrical member 2 with a central axial bore 4. A plurality of further bores 6 are slanted with respect to the central axial bore 4. Jaws 8 each associated with a bore 6 are moveable via a jaw actuator 10. A jaw locking means 32-60 is coupled to the jaw actuator 10. The jaw locking means may move between an open position and a closed position such that the jaws may be locked within their respective bore 6 regardless of the degree of protrusion of the jaws 8 into the central axial bore 4.
