Abstract
A tool chuck may include a chuck body defining a longitudinal axis. A sleeve may be mounted on the chuck body and axially fixed relative to the chuck body. A clutch part may be provided on the sleeve. The clutch part may interact with a cooperating clutch part mounted on the power driver housing. The cooperating clutch part may be mounted on the power driver housing for movement between a first axial position in which the chuck body is rotatable together with the sleeve, and a second axial position in which the chuck body is rotatable relative to the sleeve to actuate the tool chuck. The chuck body may be rotatable in a first direction to actuate the tool chuck up to a first torque threshold, and rotatable in a second direction to actuate the tool chuck up to a second, different torque threshold.
