Sandvik Coromant SCMT 432-UR 435 Carbide Insert

Sandvik Coromant SCMT 432-UR 435 Carbide Insert is a square turning insert from the CoroTurn 107 family, designed for external turning with a 1/2" inscribed circle (SCMT 432) and a UR chipbreaker for controlled, breakable chips. The ANSI code SCMT 432-UR 435 identifies the insert by size, chipbreaker geometry, and grade, and it is a carbide insert compatible with standard SCMT tool holders. CoroTurn 107 SCMT-UR inserts are commonly used for turning steel and cast iron, with coatings often described as CVD TiCN+Al2O3+TiN to boost wear resistance. Catalogs and supplier listings show SCMT-UR variants across grades such as 4315, 4325, 4335, and 4425, all within the 432 size family, offering different wear resistance and toughness options.
