Abstract
A cutting insert kit, including a base part formed of a brittle and wear-resistant material, and a plurality of cutting insert blanks integrally formed with the base part, which are separable one by one from the base part via indications of fracture. Each insert blank includes a front end portion, a rear end portion, an upper side, an under side, and at least one cutting edge in the front end portion formed between a clearance surface and one of the upper and under sides. The base part is common to all cutting insert blanks and to which each cutting insert blank is united to the base part via an indication of fracture in the form of a weakened connection member between the base part and the rear end portion of the cutting insert blank.
