<p>A keyless chuck having both an automatic locking feature and a manual locking feature. The automatic locking feature (90,92,68) provides for automatic locking of the chuck in a tightened state when a predetermined tightening torque has been exceeded. The chuck can be utilized with only the automatic locking feature engaged. If desired, a manual locking feature can also be engaged wherein rotation of the outer sleeve (42) relative to the body (28) is prevented. A retaining feature can be employed to inhibit the movement of the manual locking feature between a locked and unlocked position. The retaining feature (84,86,58) thereby avoids accidental engaging or disengaging of the manual locking feature (82,56).</p> |
