ABSTRACT:
An improved collet lock arrangement for a hand-held power tool having a housing is provided. The collet lock arrangement includes a powered rotatable shaft including a base portion and distal end portion defining a collet for adaptably connecting a driver tool attachment thereto and a locking structure for securely locking the shaft to the housing to selectively prevent the shaft from rotating when in a locked position while allowing the shaft to freely rotate in an unlocked position. The locking structure has a locking sleeve coaxially coupled around the shaft for axial movement relative thereto between the locked and unlocked positions, a clamp nut fixedly connected to the housing, and a sleeve guide non-rotatably coupling the locking sleeve to the clamp nut. The clamp nut and sleeve guide are coaxially arranged for coaxially receiving therethrough the shaft and the locking sleeve. During axial movement of the locking sleeve from the unlocked position to the locked position, a portion of the locking sleeve is slidably matingly engaged between the base portion of the shaft and the guide to lock the shaft against rotational movement.
