Recently, various film coated insert tools have been used in order to improve tool life by several different vapor deposition or chemical vapor deposition. Especially, TiN coated drills have been broadly studied because of improving drill performance in terms of drill life, work quality and its brilliant color. Nevertheless, because of the poor adhesion between TiN film and drill, it was difficult to attain the better drill performance. Therefore, to improve adhesion of TiN films, we sputtered titanium as interlayer prior to TiN deposition on drill by PECVD(Plasma Enhanced Chemical Vapor Deposition). The results indicate that Ti/TiN coated drills achieve about 2.6 times life improvement, while TiN coated drills only 2 times. Wear characteristics of tested drills were examined using SEM, and the results were correlated with drill life and roughness of drilled holes.
