DCMT11T3**-UF Inserts for Steels - Finishing

Machining Materials

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

Chipbreaker

• (UF) - Geometry specially designed for finishing on steels. It features a small rake angle (rake angle) and is available with small cutting radii (RE). Suitable for small cutting depths (Ap) and low feeds (Fn). Ensures excellent surface quality.

Grade

• YG3115 – New grade for high machining speeds on steels (P15–P25). CVD MT-TiCN–Al₂O₃ coating. Ideal for mass production with stable tool life and minimization of built-up edge formation.

Feed

• Fn = 0.05~0.25 mm/rev

Cutting Speed

• (P1-5) - Vc=180~500 m/min
• (P5-9) - Vc=170~450 m/min
• (P10-11) - Vc=60~300 m/min

Turning inserts from YG1, a leading cutting tool manufacturer from Korea. The choice of the appropriate insert depends on the chipbreaker, that is, the geometry that helps in breaking and removing the chip, as well as on the grade, which describes the microstructure and coating of the insert and directly affects hardness and fracture toughness. The cutting conditions (speed, feed, depth) must be carefully defined to achieve maximum performance and tool life.
