TNMG2204**-UG Inserts for Steels - Continuous Cutting

Processing Materials

• (P) - Steels - Alloy Steels (Steel - Alloy Steel)

Chipbreaker

• (UG) - Geometry for general machining of steels. It 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)

Grade

• YG3125 – First choice for steel machining (P15–P35). New grade with high heat resistance and for interrupted cutting. CVD MT-TiCN–Al₂O₃ coating with final TiN layer for wear control and easy recognition of worn edges. Surface treatment that reduces built-up edge formation and improves chip removal. Ideal for continuous and interrupted cuts in mass production applications.

• YG3030 – Ideal for interrupted cutting in steel and stainless steels (P20–P35). New CVD TiCN - Al₂O₃ coating technology. Substrate specially designed for high toughness and balance of wear and coating chipping resistance

Feed

• Fn = 0.20~0.40 mm/rev

Cutting Speed

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

Turning inserts from YG1, a top 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.
