Abstract
A chuck has a generally cylindrical body member having a nose section and a tail section. The tail section is configured to mate with the drive shaft so that the body rotates with the drive shaft. The nose section has an axial bore formed therein and a plurality of jaws is slidably positioned to engage a bit within the axial bore. Each of the jaws has a bit engaging jaw face formed thereon. One or more centering members are disposed adjacent to the jaws. The members are deformable from a first position where the members define a through passage configured to accept a bit, which has a drive shaft diameter less than a predefined diameter. The members are further configured to be deformable to a second position upon the insertion of a bit, which has a diameter greater than the predefined diameter, into the axial bore.
