In this study, we examined the relationships between the coating film`s properties, such as microhardness, adhesion of coating fil $m_strate, and machining tool`s life time. Samples were prepared by coating TiN on the 5.5 diameter twist drills using reactive ion plating technology, For measuring microhardness and adhesion of fil $m_strate, HSS plate was used for substrate. TiN coated drill`s life time was dependent on the adhesion of fil $m_strate and averagely increased by several ten times more than uncoated drill`s. The major parameter affecting TiN coated drill`s life time was the strong adhesion between coating film and substrate.ate.
