A tool such as a milling or drilling tool includes a shaft having a front recess in which a cutting head is disposed. A drawbar disposed in the shaft includes a plurality of flexible tongues disposed in the recess. The tongues form a recess in which a rear knob of the cutting head is received. A retainer urges the drawbar axially rearwardly to retain the cutting head in the recess. The shaft includes axial projections at its front end which are received in respective rearwardly open recesses of the cutting head to prevent relative rotation between the shaft and the cutting head. |
