Workpiece Materials

• (M) - Stainless Steels (Stainless Steel - Inox)

Chipbreaker

• (UF) - Geometry specially designed for finishing steels. 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

• YG1010 – Ideal choice for cast iron (K05–K15). CVD TiCN–Al₂O₃ coating with special post-treatment for increased coating fracture resistance.

Feed

• Fn = 0.03~0.20 mm/rev

Cutting Speed

• (K15-16) - Vc=300~450 m/min
• (K17-18) - Vc=120~350 m/min

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 fracture toughness. The cutting conditions (speed, feed, depth) must be carefully defined to achieve maximum tool performance and life.
