21/64″ Mechanics Length Drill Bit – M-7 High-Speed Steel, Black & Gold Oxide, 135° Split Point, 3-Flat Shank – Precision Metal Drilling

The DBDFML-21/64 mechanics length drill bit is constructed from M-7 molybdenum high-speed steel and finished with a black and gold oxide coating to enhance wear resistance, reduce friction, and extend bit life. Its 135° split point provides quick, accurate starts without walking, making it ideal for tough drilling jobs. The 3-flat shank design prevents the bit from slipping in the drill chuck. The shorter mechanics length increases rigidity, helping maintain precision in tighter or awkward workspaces.
