This is a new, factory-packaged set of 6 Chicago-Latrobe List 250AN #16 wire gauge twist drill bits (part number 47475), manufactured in the USA. The List 250AN series is a jobber-length HSS (high-speed steel) drill ground to a 118° conventional point angle with a straight shank, designed for general-purpose drilling in steel, cast iron, aluminum, and similar materials. The steam-oxide (black oxide) finish visible on the flutes provides mild corrosion resistance and reduces friction during cutting. Wire gauge #16 corresponds to a diameter of 0.177 inches (4.496 mm), and jobber-length geometry provides the standard flute-to-shank length ratio suited for use in drill presses, CNC machining centers, and hand-held power drills with a standard 3-jaw chuck. The quantity of 6 pieces per package is confirmed on the label (QTY: 6).
