A collet assembly for releasably holding a tool shaft of the type having an indexing depression in the surface thereof includes an elongate core having a bore in one end thereof for receiving the tool shaft. A retainer extending transversely through the core is shiftable into a locking position within the depression in order to prevent rotation of the shaft relative to the core. A tapered sleeve longitudinally slidable over the core engages and drives the retainer into the core. A collar threadably mounted on a core draws the sleeve in one longitudinal direction over the core in order to maintain the sleeve in a position locking the retainer in place.
