    5/16″ Mechanics Length Drill Bit – M-7 High-Speed Steel, Black & Gold Oxide, 135° Split Point, 3-Flat Shank – Metal Drilling Precision Bit

    Part #: DBDFML-5/16

    The DBDFML-5/16 mechanics length drill bit is crafted from M-7 molybdenum high-speed steel for reliable performance in tough metalworking applications. It features a black and gold oxide finish that enhances lubricity, reduces friction, and improves chip evacuation. The precision-ground 135° split point enables quick starts with minimal walking. A 3-flat shank design locks securely in the chuck to prevent slippage, and the mechanics length format adds rigidity for cleaner, more accurate drilling.
