TPKN Face milling insert
SOMT square face milling inserts feature 4 cutting edges for cost efficiency, with complete sizes and corner radii. Special clamping design boosts rigidity & positioning accuracy; optimized chip groove delivers smooth cutting and chip evacuation. Two yellow PVD coated grades P20 and P20A are available. P20A adopts ultra-fine TiAlN nano coating with rare elements for superior heat & wear resistance, while P20 suits semi-finishing & finishing of stainless steel. They perform well on steel, stainless steel, cast iron and light interrupted cuts. A 5-point selection guide and professional tool consultation are offered.
