摘      要：Coated tools are widely used in today’s metal cutting industries and have significantly improved machining productivity through reducing operation costs and time. This paper presents the results of a systematic study of the performance of HSS drills coated with CrTiAIN and drills with a top solid lubricant coating of MoST?. The tests were performed on a Haas vertical machining centre under wet and dry cutting conditions to machine through holes in medium carbon steel workpieces. The feed force and torque were recorded throughout some of the tests using a force dynamometer, while the tool wear was monitored and measured. It was found that MoST? coatings even under accelerated conditions improve the tool life significantly based on their unique properties and very low friction.
