Nachi 1270836 List601 2-5/32 HSS Taper Shank Drill General Purpose Regular Shank

This is a new Nachi List 601 high-speed steel (HSS) taper shank twist drill with a 2-5/32 in (2.15625 in / 54.77 mm) cutting diameter and a general-purpose regular-length shank, made in Japan. The List 601 series features a black oxide surface treatment for corrosion resistance and reduced friction, a standard 118° point angle, and a conventional two-flute spiral design suited for drilling steel, cast iron, aluminum, and general-purpose ferrous and non-ferrous materials. The taper shank — a Morse Taper No. 4 (MT4) per ANSI/ASME B94.11M standards for this diameter range — mounts directly into compatible taper-socket spindles, drill press quills, lathe tailstocks, and boring mills without requiring a chuck. Nachi tooling is manufactured to strict Japanese Industrial Standards (JIS), ensuring consistent diameter tolerance, runout, and surface finish on every production unit; this drill ships in its original Nachi red box (item ID NAC1270836).
