This study reports an extended investigation on the wear, cutting forces and temperature on TiAlN, TiN coated and K15 carbide tool coated and uncoated tungsten carbide tools during the turning of four grades of ductile cast iron. During the machining of low strength grades, the flank wear rate was considerably lower and the steady-state longer, furthermore adhesion was observed on the rake and clearance faces. In the machining of high strength grades, the high wear resistance of the coated TiAlN coated tool caused a steady-state behavior then the flank wear rate change drastically. The K15 carbide tool had the worst performance respecting cutting force and flank wear. Although the cutting forces were similar for both coated tools, the TiAlN coated tool has better performance concerning to flank wear.
