Method for producing a tool part and such a tool part

A method for producing a metal cutting tool component, comprising the steps of:

• producing a front module, the front module including a main body and a front module interface, comprising the steps of:
• providing an intermediate element, comprising providing the front module interface at a rear end of the intermediate element and a build surface at a front end of the intermediate element;
• and
• building, using an additive manufacturing process, the main body on the build surface of the intermediate element;
• providing a rear module comprising providing a coupling part at a rear end of the rear module and a rear module interface at a front end, of the rear module;
• after producing the front module and providing the rear module, mounting the front module on the rear module by immovably connecting the front module interface and the rear module interface;
• after the front module has been mounted on the rear module, machining at least one surface of the main body;
• and
• heat treating the front module, wherein at least the main body is hardened, wherein the front module is heat treated separately from the rear module.
