Abstract
A torque transmitting tool is machined by registering the torque transmitting tool using a shoulder between the shank and the out-of-round drive portion of the tool as a reference. First and second seating surfaces are milled on first and second opposed surfaces of the tool, and then first and second bores are drilled into the drive stud, starting from the first and second seating surfaces, respectively. The first and second bores intersect within the drive stud to form a stepped diagonal bore in the tool. Alternately, all machining operations are performed from one side of the tool.
