ABSTRACT:
A torque tool comprises a torque converter, a power tool for actuating the converter and an attachment adapter, interposed between the torque converter and the power tool, for coaxially and firmly interconnecting the former to the latter. The power tool, having its chuck removed, includes, at its front part, an outwardly extending shaft of tubular configuration incorporating a dead hole of hexagonal cross-section. The torque converter includes several coaxially successive planetary gear assemblies, first of which being driven by a first sun gear. The latter together with a hexagonal shaft form a unitary element. The hexagonal shaft is shaped and sized to fit and drivingly engage the dead hole of the outwardly extending shaft.
