ZZ Hardmetalis a professional manufacture of cemented carbide cutting tools. Our turning inserts for steel processing with imported raw powder materials, through a special sintering process, have a peculiar gradient cobalt-rich on surface of the substrates which can ensure the inserts’ high performance when finishing the CVD coating. Our CVD coating is the most advanced in the world. The coating materials are MT-TiCN0-Al2O3 with thickness of 14um, which have high abrasion resistance. After special management on the surface of the coating inserts, the internal stress and surfaceness of coating were reduce while cutting resistance was also cut down. Our ZPS series grade can cutting steel and alloy steel from finish machining to semi-finish and rough maching.
