Claim 0:
1. A torque tool comprising:
multiple bits each of which comprises a colored area;
a handle for connection to a selected one of the bits, wherein the handle is operable to set multiple maximum values of torque transferable to the bit from the handle corresponding to the colored areas of the bits;
a label supported on the handle, wherein the label comprises multiple colored areas corresponding to the colored areas of the bits and multiple numbers located in the colored areas of the label corresponding to the maximum values of torque;
a pointer formed on the handle; and
a scale ring rotated around the handle as the handle is operated to set the maximum values of torque, thereby aligning the pointer with a value on the scale ring according to one of the numbers in a corresponding one of the colored areas of the label corresponding to the colored area of a selected one of the bits.
