It has the advantages of high strength and good impact resistance. The unique cutting edge design ensures sharp edge and good chip breaking performance. It is suitable for the processing of materials of carbon steel, alloy steel and austenitic stainless steel.Perfect coating obviously improves abrasion resistence and anti-breakage of inserts ,also new coating technology providers better wear resistence and toughness.Improved remain internal stress design ensures good toughness and anti-cracking performance.Polishing treatment on coating surface make it suitable for cutting adhesive materials .
