GOODELL PRATT ARCHEMEDIAN STYLE SPIRAL DRILL - 1895 PATENT

Total length measures 16" This is the first one of these I have seen and I can't seem to find any references on line. Very well made and clearly stamped on the chuck 'GOODELL-PRATT COMPANY GREENFIELD MASS U.S.A. PAT AUG. 13 1895'. Spins continuously in one direction whether you are moving the grip up or down.
