Drill America jobber length drill bit features heavy-duty construction and heat treated body for optimum wear resistance and support of the carbide tip. Used in the production of cast iron, non-ferrous metals, and many composite materials such as hard rubber or copper alloys. Not recommended for drilling steel. Carbide-tipped tools feature cutting edges of carbide for wear resistance and a steel shank for toughness. Available with polished finish. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging.
