Abstract:
A tool having a relatively ductile working end for engaging workpieces and a relatively hard non-working portion for driving the tool is disclosed, and a process for making same. The tool is formed with the material in a first state, such as by cold-working, and then only the non-working portion is heat treated to a second state. The working end is thus maintained in the ductile state while the non-working portion is hardened, thus imparting different materials performance characteristics to working end and non-working portion.

Claim (Index 21):
A method for heat treating a tool, the method comprising the steps of:\n forming the tool with a stem portion having a first end adapted to couple to a driver and receive an amount of torque from the driver, a shoulder portion extending from the stem portion opposite the first end, a working portion extending from the shoulder portion opposite the stem portion and including a recess adapted to receive a device adapted to engage a work piece, and a zero-treatment region extending from the working portion to an end of the tool and forms only an opening of the recess; heat treating the stem portion to a first depth to form substantially tempered martensite steel to the first depth, wherein the first depth is measured in a radial direction from an external surface of the stem portion towards a center of the stem portion; and providing no direct heat treatment to the shoulder and working portions and the zero-treatment region, wherein the shoulder and working portions are at least partially comprised of a material including tempered steel created by residual heat from the heat treating, and are substantially free of tempered martensite steel after the heat treating, and wherein the zero-treatment region is comprised of a material free of tempered martensite steel and tempered steel.
