3/8″ Mechanics Length Drill Bit – M-7 High-Speed Steel, Black & Gold Oxide, 135° Split Point, 3-Flat Shank – Heavy-Duty Bit for Metal Drilling

The DBDFML-3/8 mechanics length drill bit is engineered from premium M-7 molybdenum high-speed steel, delivering reliable strength, heat resistance, and durability during demanding metal drilling tasks. The black and gold oxide finish reduces friction, resists wear, and enhances chip flow. A precision-ground 135° split point prevents walking and ensures quick, accurate starts. The 3-flat shank eliminates spinning in the chuck, while the mechanics length design increases rigidity and improves control in tight or shallow drilling applications.
