The Nachi List 601 (L601) is a high-speed steel taper shank twist drill, 1-27/32" diameter with a Morse Taper 5 (MT5) shank, manufactured in Japan to general-purpose regular-shank dimensions per Nachi's List 601 standard. Constructed from M2-grade HSS, it carries a black oxide surface treatment that provides mild corrosion resistance and reduces friction during chip evacuation on entry. The 118° conventional split-point geometry suits general-purpose drilling in steel, cast iron, aluminum, and similar workpiece materials on drill presses, radial arm drills, and machine tools equipped with a MT5 spindle or sleeve. Right-hand cut, right-hand helix; this drill ships new in the original Nachi red box, unsharpened from the factory.
