Abstract
A tool combination includes a bit socket with a hole extending axially therethrough and having a square drive portion and a hexagonal portion and a circularly cylindrical retaining portion between said drive portion and said bit portion, the portions being of successively smaller width from the drive end to the bit end. A hexagonal bit has an application end and a coupling end, the application end being insertable into the hole from the drive end thereof. The coupling end is provided with a retainer in the form of either an enlarged head or a laterally projecting ear which seats in the retaining portion of the hole, with the application end of the bit projecting forwardly from the bit end of the socket. An associated drive lug, when received in the drive portion of the hole, retains the bit place.
