Machining Materials - - (P) - Steels - Alloy Steels (Steel - Alloy Steel)

Former - - (UG) - Geometry for general machining of steels. Features a relatively large rake angle (rake angle) for smoother chip flow and a reinforced cutting edge with a flat section on the edge (T-land). Suitable for medium machining and continuous cutting. Combines toughness (toughness) and high wear resistance (wear resistance)

Quality - YG3125 – First choice for steel machining (P15–P35). New grade with high heat resistance and interrupted cutting. CVD MT-TiCN–Al₂O₃ coating with final TiN layer for wear control and easy recognition of worn edges. Surface treatment reduces built-up edge formation and improves chip evacuation. Ideal for continuous and interrupted cuts in mass production applications. - - YG3020 – First choice for general steel machining (P15–P30). CVD TiCN–Al₂O₃ coating. Substrate specially designed for high toughness and smooth surface for increased wear resistance.

Standard F and ap Values - - Fn = 0.20~0.40 mm/rev

Standard Vc Values - - (P1-5) - Vc=160~380 m/min - (P5-9) - Vc=140~320 m/min - (P10-11) - Vc=60~130 m/min

General Information - Turning inserts from YG1, a leading cutting tool manufacturer from Korea. The choice of the appropriate insert depends on the chipbreaker, i.e., the geometry that helps break and remove the chip, as well as the grade, which describes the microstructure and coating of the insert and directly affects hardness and toughness. The cutting conditions (speed, feed, depth) must be carefully set to achieve maximum tool performance and life.
