摘要:
A carbide cutting tip including a rear surface and a bottom surface for mounting the tip to a cutting tool tooth, a top surface having a pair of peaks separated by a trough, the top surface including a frontward facet and a rearward facet sloped downwardly and rearwardly at a non-zero angle α with respect to the frontward facet, and a front surface having a substantially flat lower portion and a concave upper portion having a shape defined by a segment of an ellipse, the lower portion being disposed substantially perpendicularly to the frontward facet of the top surface, the lower portion and the upper portion joining at a break point located at the apex of the major axis of the ellipse, the major axis of the ellipse being canted frontwardly from the break point at a non-zero angle β with respect to the lower portion of the front surface.
