A quick change tool holder of the block tool type wherein a tool nose assembly is releasably secured to a drive member at an interface plane. A bayonet subassembly extends coaxially from the drive member by some predetermined distance and is receivable in an axially extending socket in the tool nose. The bayonet subassembly is selectively rotatable relative to the drive member between engaged and disengaged conditions with the tool nose socket. The distance that the bayonet subassembly extends from the drive member is selectively adjustable for insuring that the bayonet securely engages with the socket.
