We could prodce different standards threading inserts, all items are made by general-purpose grade M25, which could apply for different workpiece. The excellent hardness and wear resistance. All grinding process are employed auto-cnc, which could get great tolrence, smooth surface. The 3 µm coating thickness, TiN+TiAlN multi-layer coating has perfect smooth surface and improve the performance of threading Inserts. It is your best cost effective selection. Whynot take a try to cut down your cost of process?
