ABSTRACT:
A drill assembly has a drill housing, a spindle projecting from the housing along an axis and rotatable about the axis, a chuck body fixed on the spindle, jaws on the chuck body, and a rotatable tightening body. The jaws move radially together on rotation of the tightening body in the forward direction on the chuck body and radially apart on rotation of the tightening body in the reverse direction on the chuck body. A setting element rotationally fixed on the drill housing is displaceable axially on the chuck body between axially offset end positions and formations between the setting element and the tightening body rotationally couple the setting element with the tightening body only in one of the end positions of the setting element. A latching element on one of the bodies can move between a locking position engaging the other of the bodies and arresting the tightening body rotationally on the chuck body and an unlocking position disengaged from the other body. A spring urges the latching element into the locking position and interengaging formations on the latching and setting elements displace the latching element into the unlocking position when the setting element is in the one end position so that in the one end position of the setting element the tightening body is rotationally locked to the drill housing and in the other end position of the setting element the tightening body is rotationally locked to the chuck body.
