21/64″ Heavy-Duty Jobber Drill Bit – HSS – Nitride Coated – 135° Split Point – Reduced Friction – DBDFNP-21/64

This 21/64″ heavy-duty jobber length drill bit is engineered for production and high-load maintenance applications. Made from premium M-7 molybdenum high-speed steel, it features a black and silver nitride treatment that enhances edge hardness, increases lubricity, and reduces heat generation. Its 135° split point geometry ensures accurate starts without wandering while reducing thrust pressure. The bit’s web design provides structural strength and rigidity for difficult materials, while the specialized margin clearance reduces friction for faster, cleaner holes. Ideal for stainless steel, titanium, mild steel, nickel alloys, and non-ferrous metals.
