Abstract
The invention relates to a cutting insert () for installation in carrier tools for machining workpieces, comprising a top side (), a bottom side (), and side surfaces () connecting the top side () and the bottom side (), wherein a peripheral protective chamfer () having an upper edge () adjoining the top side () of the cutting insert () and having a lower edge () adjoining the side surfaces () is arranged at the transition from the top side () to the side surfaces (), wherein the upper edge () forms cutting edges () and cutting corners () and, in the region of the cutting edges (), the lower edge () transitions into a cutting-edge clearance angle surface () having an edge clearance angle of 3° to 11°. For improved edge stability in drawn cuts, it is proposed that, in the region of the cutting corners (), the lower edge () of the protective chamfer () transitions into a corner clearance angle surface () having an edge clearance angle of 3° to 5°.
