27/64″ Mechanics Length Drill Bit – M-7 High-Speed Steel, Black & Gold Oxide, 135° Split Point, 3-Flat Shank – Metal Drilling Bit

The DBDFML-27/64 mechanics length drill bit is built from M-7 molybdenum high-speed steel, designed for heavy-duty performance and long-lasting durability in metal drilling. Its black and gold oxide surface treatment reduces friction and increases wear resistance. A precision-ground 135° split point ensures fast starts with reduced walking, while the 3-flat shank locks into the chuck to prevent rotation. The mechanics length configuration improves rigidity and allows more precise drilling in tighter or angled spaces.
