ABSTRACT:
A tool extension adapter is provided which is adapted to be coupled to a tool drive for permitting the attachment of two different sized tools, for example socket wrenches, to a tool drive such as an air gun or ratchet using the same tool extension adapter merely by reversing the tool extension adapter in the tool drive. The adapter includes a extension bar of different first and second lengths with different first and second predetermined outside dimensions one of which is less than the other to accommodate different sized tools. A plurality of detents are positioned in the extension bar for coupling the reversible extension bar of different end sizes to the tool drive either directly in an impact or with a sleeve coupling to a ratchet tool drive. This permits the use of one tool extension for accommodating two sizes of sockets which prior hereto required two extensions for the different sizes desired.
