Digital Tripper,
A number #80 drill bit is extremely tiny. At .03125 diameter it is about the thickness of a guitar string. Usually drills this small are drilled with a machine called a sensative drill press with an Albrecht keyless chuck. The slightest wobble in the bit will equal a large percentage of the drill bit diameter. If you are drilling through steel this can be devistating. If you do not have the proper drilling equipment try drilling through a softer material such as brass. Make sure that the drilling operation is done with an extremely light touch and do not try drill too deeply with each peck. Although brass can in theory be drilled dry, a lubricant (oil) will be helpful.
