Cutting insert kit, method for manufacturing cutting inserts and a cutting insert for a cutting insert kit

A method of manufacturing cutting inserts for chip removing machining, comprising:

• forming a base part of a brittle and wear-resistant material;
• forming a plurality of cutting insert blanks integrally with the base part, which are separable one by one from the base part via indications of fracture;
• forming each insert blank to include 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;
• forming the base part common to all cutting insert blanks such that 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;
• and
• separating at least one cutting insert from the base part by fracturing the weakened connection member.
