ABSTRACT:
A chamfering tool made up of a holder and a double headed blade. The holder is substantially cylindrical, with a bullet nose at one end and a turned down shank at the other end. An angularly offset bore for holding the blade penetrates the bullet nose at an angle to the holder longitudinal axis, and also penetrates the holder cylindrical wall. When the blade is installed in the bore, one or both heads externally expose their respective operating cutting edges. The blade is substantially cylindrical, with cutting edges at each end being perpendicular to and intersecting the longitudinal axis of the blade. The novel arrangement enables the chamfering tool to work in tight quarters, to be readily removed and easily sharpened, and enables both right and left handed cutting by a simple adjustment.
