ABSTRACT:
A method and device for testing a substantially cylindrical tool having an axis is performed by imparting a testing torque to the cylindrical tool. The tool is clamped in a vise. The tool has a driven end including a shank and a working end in opposed relation along the axis. The vise is configured to clamp the tool to prevent rotation of the tool about the axis. The shank is clamped in a chuck. The chuck has a adapter defining a void configured to engagingly receive a socket drive shaft. A torque wrench having a lever arm and a socket driver shaft is engaged by insertion of the socket drive shaft into the void. A torque is imparted to the cylindrical tool about its axis by suitably imparting a force on the lever arm. The quantum of torque imparted is measured based upon operation of the torque wrench.
