Abstract
A cutting tip including a cutting edge portion made of a high-hardness material to take a thin-plate shape; and a support portion made of a material which is more worn in contact with a workpiece than the cutting edge portion not to exert a machining action on the workpiece even in contact with the workpiece, and securing and supporting the cutting edge portion on a reverse side of a rake face of the cutting edge portion. Thus, the width of flank wear is prevented from increasing and chipping of the cutting edge is prevented, so that the life of the cutting tip can be extended.
