ABSTRACT:
A single-point metal machining cutting tool takes the form of an elongated bar whose opposed ends are provided with transverse flat bottom, flat wall grooves intersecting the axis of the bar. Tip holders of complementary flat wall configuration may be mounted within the grooves, held in position by a screw passing through the tip holder at its center and received within a tapped and threaded axial hole within the ends of the cutting tool bar. Shear forces during cutting are not transmitted from the tip holder to the bar through the screw, strain on the screw is eliminated, and the ability of the bar to withstand torque during cutting is maximized by the axial location of a single screw hole at each end.
