SCMT1204**-PM Cermet Inserts for Steel, Cast Iron, and Stainless Steel - Finishing

Workpiece Materials

• (P) - Steels - Alloy Steels
• (M) - Stainless Steels (Inox)
• (K) - Cast Irons

Chipbreaker

• (PS) - Geometry specially designed for finishing on steels, stainless steels, and cast irons. It features a small rake angle and is available with small cutting radii (RE). Suitable for small cutting depths (Ap) and low feeds (Fn). Used for cermet grades. Ensures excellent surface quality.

Grade

• YT100 – New generation general-purpose cermet (P10–P20 / M10–M20 / K10–K20). Increased wear resistance, with a special surface for top finishing.

Feed

• Fn = 0.06~0.25 mm/rev

Cutting Speed

• (P1-5) - Vc=150~480 m/min
• (P5-9) - Vc=160~480 m/min
• (P10-11) - Vc=70~180 m/min
• (M12-13) - Vc=120~180 m/min
• (M14) - Vc=130~260 m/min
• (K15-16) - Vc=130~450 m/min
• (K17-18) - Vc=100~400 m/min

Turning inserts from YG1, a top 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 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 set to achieve maximum tool performance and life.
