PCT No. PCT/DE92/01027 Sec. 371 Date Jun. 10, 1994 Sec. 102(e) Date Jun. 10, 1994 PCT Filed Dec. 7, 1992 PCT Pub. No. WO93/11898 PCT Pub. Date Jun. 14, 1993The invention relates to a cutting insert for chip-forming machining, in particular for roughing of metallic work-pieces with a high feed speed. To increase the chip movement during cutting it is suggested that indentations (14) be provided in the region of a cutting edge (12) which are arranged in a row extending along the cutting edge (12), which interrupt same and which have a generally trapezoidal sectional shape parallel to the cutting edge (12) and perpendicular to the chip surface (10) with trapezoidal sides open toward the chip surface, the indentations having a chip-surface base extending at a negative or 0 DEG chip angle (19) to the cutting edge (12), the chip surface (16) in the region between the indentations (14) at the cutting edge (12) has a positive chip angle (17).
