The T490-LNHT130612PNTR insert is primarily used as the core cutting element for tangentially clamped T490 milling cutters, directly participating in square shoulder milling, face milling and slotting to remove material efficiently. It is typically used in combination with T490 series milling shanks and cutter bodies to achieve high feed speed, stable cutting performance and excellent machining efficiency, especially crucial for heavy roughing and semi-finishing on steel, stainless steel, cast iron and superalloy workpieces. It is suitable for mold processing, automotive parts, hydraulic components, general machinery, engineering machinery and aerospace auxiliary component manufacturing.
