Extra-long length drill bit reaches farther and drills deeper than a jobber or long length drill bit * High-speed steel (HSS) provides hardness for wear resistance * Black oxide finish reduces wear while promoting chip and coolant flow on ferrous materials * Self-centering 118-degree notched point penetrates material without a pilot hole more easily than a conventional point, and maintains a sharp cutting edge * Extra thick web provides increased strength and rigidity compared to standard drill bits
