The LNHU130612R / LNHU130608 inserts are primarily used as the core cutting elements for tangentially clamped T490 milling cutters, directly engaged in square shoulder milling, face milling and heavy slotting for efficient material removal. They are commonly matched with T490 series cutter bodies and milling shanks, delivering high feed rates, outstanding impact resistance and stable cutting performance, especially suitable for roughing and semi-finishing of steel, stainless steel, cast iron and high-temperature alloy workpieces. They are widely applied in mold manufacturing, automotive parts, hydraulic components, general machinery, construction machinery and aerospace auxiliary part production.
