This paper deals with the machinability of BN Added Steels in turning with several cutting tools. The highest Al content TiAIN coated carbide tool showed smaller flank wear and crater depth than those of the other TiAIN, TiC, TiN and TiCN coated carbide tools. It shows that these tool wears depend on the affinity between tool surface and adhered layer including AIM. The wear of the alumina ceramic tool in turning BN added steel was smaller than that in turning standard steel. However the wears in turning low Al content BN added steel and high Al content carbon steel were almost the same as that in turning standard steel. It shows that appropriate Al and BN in work material are necessary to obtain the longer tool life. The wears of the TiC added alumina ceramic tool and the CBN tool in turning BN added steel were also smaller than those in turning standard steel.
