Abstract
A thread-cutting insert includes opposite top and bottom sides as well as front and back sides, the front one of which is formed with a plurality of laterally spaced-apart teeth, which separately have a chip-removing edge in a transition between a clearance surface and a top surface of the individual tooth, one the of the teeth, viz. a final-shaping tooth, having a contour shape that gives the desired profile shape of the thread that is to be generated. At least one downwardly open duct is formed in the bottom side of the cutting insert, which duct extends up to the final-shaping tooth and ends adjacent to the same. Advantageously, such ducts are formed for all teeth.
