#1 MORSE TAPER ROUGHING REAMER, T.S.#1 MORSE TAPER ROUGHING REAMER, T.S. 5380001, #1 MORSE TAPER SHANK, HSS .517" Large End Diameter, .367" Small End Diameter, 3" Flute Length, 6-3/16" Overall Length, High Speed Steel, #1 Morse Taper Shank. Morse Taper Roughing Reamers are used to start forming tapers in straight holes and do the heavy stock removal prior to using a finishing morse taper reamer. They are also used to remove heavy nicks and burrs from machine spindles with the appropriate morse taper size, but we would recommend a finishing reamer for that application. The taper is approximately 5/8" per foot and we stock these reamers in a finishing style with either a straight shank or taper shank, then this roughing style with a taper shank.
