Screw Machine Drill Bit, Fractional Inch, 3/8", 0.3750, 135, High Speed Steel, Black Oxide
These drill bits have a black-oxide finish that retains lubricants to improve the bits' wear resistance and chip flow. Black-oxide bits should only be used for drilling ferrous metals. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.
