Nachi List 651 13/32x18" MT1 HSS Extra Length Taper Shank Drill Bit

This is a new Nachi List 651 extra-length taper shank drill bit in 13/32" diameter with an 18" overall length and a #1 Morse taper (MT1) shank, as clearly labeled on the original box. Manufactured from high-speed steel (HSS), Nachi's List 651 series is a standard-geometry, two-flute twist drill ground to ANSI/ISO tolerances with a conventional 118° point angle, designed to deliver consistent hole quality in steel, cast iron, aluminum, and other common engineering materials. The extra-length (XL) flute geometry provides reach for deep-hole drilling applications where a standard-length drill cannot access, and the MT1 taper shank seats directly into any MT1-compatible spindle or drill press quill, eliminating the need for a separate chuck. The drill exhibits the characteristic bright/uncoated HSS finish visible in the product photos, consistent with Nachi's standard List 651 production specification.
