The invention relates to a cutting insert (10) made of cemented carbide and to the use thereof for recessing or copy-turning, preferably at a high rotating speed. The cutting insert has at least one recess (2) for insertion therein of a cutting body (3) consisting of a cutting material different from cemented carbide to form a firm connection, the cutting body having formed a cutting edge thereon. To allow employment of the cutting insert of a high mechanical strength even with small dimensions in the high-temperature range, it is proposed that the cutting body consist of a ceramic cutting material and have a geometric shape at least a portion of which is congruent with the geometric shape of the recess. Preferably, the ceramic cutting body has the shape of a circular truncated cone. (FIG. 1)
