- The drill bits in these sets 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. High-speed steel drill bits provide some flexibility and absorb some shock and vibration.These sets contain multiple hex-shank drill bits in different sizes. They ensure users have a range of bits on hand for maintenance and repair tasks. The bits' hexagonal shank provides maximum surface contact with a drill chuck on handheld power tools. This prevents the bits from slipping in the chuck and allows more torque to be transmitted from the chuck to the bits during drilling. Hex-shank drill bits insert into a standard 3-jaw drill chuck or a drill chuck specifically designed for hex shanks.
