The issue of increasing the strength of cutoff and grooving tools is considered in the paper. The principle of strength balance of edge is offered to be used in designing the replaceable inserts. The calculations are made and the shape is designed for the strength balanced front surface of the cutting tools. The analysis of the received data is made and the regularities of the designed shape of the front surface of the cutting edge are established. Designs of replaceable cutting inserts made with a glance to structural characteristics and operating conditions of the cutoff and grooving tools are offered.
