The Nachi List 601 is a 1-27/32" (1.84375") diameter High Speed Steel (HSS) taper shank twist drill, new in original red Nachi packaging, manufactured in Japan to general-purpose regular shank specifications. The drill features a black oxide surface treatment — clearly visible in the photos — which provides mild corrosion resistance and improved lubrication retention during cutting. Nachi List 601 taper shank drills conform to standard jobber-length geometry with a conventional 118° point angle and are designed for drilling ferrous and non-ferrous materials in drill presses, lathes, and radial arm drills equipped with a compatible Morse Taper spindle socket. At 1-27/32" diameter, this drill takes a #4 Morse Taper (MT4) shank per standard industry sizing for drills in this diameter range. The SKU referenced on the box label is 1270458, consistent with Nachi's published catalog numbering for this size in the List 601 series.
