A power tool including a power tool body, a rotatable driven member being operable for releasably gripping a working element and having a front end and a rear end, the driven member extending from the rear end, located proximally and connected to the power tool body, and terminating at the front end. The power tool has a drive mode in which rotation of the driven member drives the working element relative to the power tool body and an adjustment mode in which rotation of the driven member causes the driven member to either grip the working element or release the working element or both. The power tool also includes a guard extending over the driven member from the power tool body and terminating adjacent to the front end of the driven member, wherein at least in the power tool drive mode the front end of driven member does not extend beyond the guard. In another aspect the guard has a surface for gripping the power tool between the front end of the driven member and the power tool body.
