Abstract:
A chuck for use with a rotary power tool having an output spindle. The chuck includes a base and an inner sleeve threadedly coupled to the base. The inner sleeve has a central aperture. A collet is disposed within the central aperture of the inner sleeve and configured to be engaged by a portion of the inner sleeve to be tightened or untightened. The chuck further includes an outer sleeve surrounding the inner sleeve, and a detent member disposed between the inner sleeve and the outer sleeve. The detent member is coupled for co-rotation with the outer sleeve and configured to selectively transmit torque from the outer sleeve to the inner sleeve. When the collet is tightened, rotation of the outer sleeve causes axial displacement of the detent member relative to the inner sleeve as the outer sleeve and the detent member rotate relative to the inner sleeve.
