This is a new Tri-Angle USA-made straight shank chucking reamer in High Speed Steel (HSS), sized at 0.2125 inches, with a spiral (helical) flute configuration as indicated by the label abbreviation 'S/FL' and confirmed by the visible flute geometry in the photos. The label code 'SPL S/S S/FL CK/RE' decodes as: Special, Straight Shank, Spiral Flute, Chucking Reamer — a configuration used for finishing drilled holes to precise diameter in machining centers, drill presses, and lathes. The 0.2125 in diameter corresponds to a #3 taper or straight reamer size used in close-tolerance bore finishing applications in steel, aluminum, and cast iron. HSS construction provides adequate toughness for interrupted cuts and general-purpose reaming where carbide is not required. Part number on the label reads 1500-2125, consistent with Tri-Angle's product numbering convention encoding diameter in the suffix.
