It features an 80-degree diamond (rhombic) shape with a neutral hand orientation and a negative rake and side clearance geometry. The inscribed circle measures 0.5 inches, insert thickness is 0.1875 inches, and the corner radius is 0.0469 inches (3\/64 inches). The KCP40B grade carries a multilayer MTCVD coating system — TiN, TiCN, and Al2O3 — engineered to deliver high toughness in steel applications and moderate wear resistance with toughness in stainless steel. It is installed by CNC machinists and toolroom technicians on turning centers, lathes, and boring machines.\u003c\/p\u003e\u003cp\u003eThis insert is designed for roughing and medium machining operations on steel (ISO P) and stainless steel (ISO M) workpieces. Applicable operations include turning, facing, and boring. The KENLOC series insert uses a clamp and pin holding method, and with four cutting edges, it offers multiple index positions before replacement. The maximum depth of cut is 0.1691 inches, making it suitable for moderate-to-aggressive material removal passes on ferrous and austenitic alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCP40B grade with multilayer CVD coating: TiN, TiCN, and Al2O3 for wear resistance and toughness\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CNMG) with chamfered and honed cutting edge style\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended tooling economy\u003c\/li\u003e\n\u003cli\u003eMN chip breaker geometry rated for roughing and medium machining\u003c\/li\u003e\n\u003cli\u003eNegative rake and negative side clearance for maximum edge strength\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin insert holding systems in the KENLOC series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC series toolholders that accept CNMG433 inserts with clamp and pin retention.
