This is a very nice, clean, 3/8 Pipe reamer marked "MORSE TWIST DRILL & M. CO. 3/8". It is in very good condition, sharp, ready to use, with the tapered shank to fit most braces and two jaw breast drills! Measure 4.25" long, tapers from .28" to .44" over 2" fluted length. A very clean tool, no sign of use!
