The fine WC micro grain substrate with high co content gives wonderful cutting edge strength. The PVD AITiN coating combines with good thermal stablility silicon, which has very small coefficient of friction and good nano-hardness. The grade is good at stainless steel semi-finishing turning, parting and grooving processing. Also, it is a preferred grade for steel and stainless steel milling and drilling.
