Abstract
An improved self-sharpening refractory metal cutting tool presenting an overhanging cutting element of width about equal to the depth of the cut to be taken and of maximum thickness equal to tolerable tool flank wear is provided with a plurality of grooves at least on the rake face of the over-hanging cutting portion, or cutting element, to guide the chip leaving the workpiece and to reduce the cutting forces. These chip-grooves are utilized in sequence as the cutting element is consumed lengthwise during the machining operation.
