Recent technological advancements for the development in surfacing of engineering materials through coating of nano materials to enhances material and mechanical properties with improved tribological characteristics is inevitable. In the present paper an attempt is made to study the feasibility of nano coating of cutting tool materials by ceramic materials. For the present study, among the variety of cutting tools, the drills with larger length to diameter ratio are selected with small drill holes. The studies were conducted based on the penetration of coated materials over drill bits, coating technologies, characterization and experimental investigations on coated cutting tools and the cutting tools manufactured by powder metallurgy process. The various nano coating under discussion are physical vapour deposition (PVD), chemical vapour deposition (CVD), spin coating and sol - gel processes.
