45 Degree Face Milling Insert SNMX1206ANN-MM Replace PC5300 Heavy Cutting Roughing Cutter Head
This SNMX1206ANN-MM 45° face milling insert features a double-sided design with 8 usable cutting edges, engineered as a direct drop-in replacement for PC5300 grade. Purpose-built for heavy roughing and high stock removal, it delivers reliable performance on carbon steel, alloy steel, stainless steel and cast iron with standard face milling cutter heads.
Matching PC5300 in cutting performance, this insert adopts a premium PVD-coated fine-grain carbide substrate with excellent hot hardness and oxidation stability. It effectively suppresses built-up edge and crater wear, with reinforced edge strength to resist chipping and fracture under heavy intermittent roughing loads.
Manufactured to strict ISO dimensional tolerances, these inserts fit all standard 45° SNMX face milling cutter heads for fast indexing and secure clamping. With 8 cutting edges per insert, it significantly cuts tooling costs and is widely used in heavy machinery, shipbuilding and steel structure industries for heavy stock removal operations.
