ABSTRACT:
A quick release chuck device includes a body member having an internal bore for receipt of a tool shank. The body member is matable to a drive spindle. A plurality of circumferentially spaced passages are defined in the body member, with each passage defining an opening into the internal bore. Bearing members are disposed in the passages and are radially movable within the passages so that at least a portion of each bearing member extends into the internal bore. An outer sleeve is disposed about the body member and the bearing members. The sleeve is rotatable relative to the body member between a gripping position and a released position. The outer sleeve has an inner diameter surface with ramping engaging surfaces defined therein which are spaced so as to engage the bearing members and force the bearing members radially inward to positively grip a tool shank disposed in the internal bore when the outer sleeve is rotated to its gripping position. The tool shank is released by rotating the outer sleeve to its released position which allows the bearing members to move radially outward.
