Abstract
An apparatus for removably fixing a tool to the head of a handpiece including a neck having the head at one end of the neck and a handle at an opposing end of the neck, and interior portions receiving a drive shaft for rotating the tool. The apparatus includes a bore formed in the head of the handpiece, for receiving the tool in the bore of the head, and a toothless friction drive coupled with an end of the drive shaft adjacent to the bore of the head. The friction drive engages shank portions of the tool while received in the bore of the head. The tool is retained in the bore by frictional contact between the shank of the tool and the friction drive coupled with the drive shaft.
