Some cut machines are designed with inserts to enhance certain functionalities. This means that their cutting edge has a welded, brazed, or clamped separate piece of material on the machine body. To achieve this, materials such as cubic boron nitride, cemented carbide, and polycrystalline diamond are used. Changeable inserts are not available for drilling and milling machines. Hollow shank taper and shank taper are the two holders for mounting the cut machine on the CNC's machine spindle. The cutting edge of a cut machine plays a critical role during the cutting process. Good cutting edges are characterized by these following three features:
