Patent abstract
A drill includes a chuck which has a body member including a bore to receive a tool. Jaw members frictionally engage the tool to retain the tool in the chuck. A member is associated with the jaw members and the body to move the jaw members between clamping and non-clamping position. A centering mechanism extends radially into the body member to center tool bits within the chuck while prohibiting the tool bit from contacting the bore wall.
