Tri-Angle .4230-733 HSS Tapered Reamer USA

This is a new Tri-Angle (L&I, Winooski, VT) high-speed steel tapered reamer, part number 533.3015, engraved .4230-733 HSS, manufactured in the USA. The tool features a multi-flute tapered body with a straight shank, designed to finish-ream tapered holes to close tolerances; the .4230 designation indicates the small-end diameter of approximately 0.4230 inches, and the 733 suffix encodes the taper specification (taper per foot or series). Constructed from HSS, this reamer is suited for hand or machine reaming of steel, cast iron, aluminum, and other common engineering materials where a precise tapered bore is required. The fluted geometry visible in the photos is consistent with a chip-clearing design for through-hole and blind tapered reaming applications.
