The black-oxide finish on these drill bits 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. These drill bits have a shank with a tang that prevents the bits from slipping in a drill chuck. Tang-shank drill bits can be securely inserted and removed from a compatible chuck without using tools, reducing downtime.
