Abstract

See full text

A driver bit and a driving tool having a plurality of projections formed on at least one surface of the shank portion/driving portion of the bit/tool to retain the bit in a bit holder, or to retain a socket or the like on the driving tool. The projections are formed such that the geometric envelope of the bit is within the tolerance of the bit holder, so that the bit can be used with standardized holders. When torque is applied to the bit or driving tool, the projections engage the inner surface of a standardized holder/socket, thereby retaining the bit/socket.
