Flank wear was the initial tool wear pattern observed at the nose of both coated and uncoated tools. Flank wear was also increasing rapidly, which is accompanied by severe abrasive marks during cutting in both tools. At the cutting speed of 350 m/min, uncoated inserts performed well with minimum tool wear and good surface finish. At the cutting speed of 500 m/min, the coated tool resulted with maximum tool wear and minimum surface roughness. In particular, at cutting speed 500m/min the higher tool wear has been recorded.
