Wiha Torx Wing handle screwdrivers are built for high torque transfer with small screws. The wider handle creates even more torque. Wing handles have a molded wing and a top grip knob to allow for rapid spinning of the driver. Torx wing handles are commonly used in the CNC machining industry and knife maintenance. The shaft is made of premium quality tool steel for strength and durability and are through hardened for best wear resistance and have a black coating for corrosion resistance. Wihas exact fit Torx tips eliminate excessive bit wobble for increased driver accuracy. The result is a highly stable engagement with the screw head and a reduction in fastener cam out that can lead to injury or damage to finished materials.
