TNMG1604-Tungsten Carbide Turning Inserts

TNMG tungsten carbide turning inserts feature a newly developed CVD coating grade for improved durability and longer tool life. The double-sided wide-groove geometry provides excellent chip breaking, while sharp and reinforced cutting edges offer good impact, wear and chipping resistance. Multiple geometries and corner radii are available for finishing, medium cutting and roughing of quenched and tempered steel, forged materials, die steel and hard steel.
