PURPOSE: A cutting tool is provided to create a wear-resistant cutting tool, as well as an efficient process for its production. CONSTITUTION: At least certain regions of a cutting tool(1) and cutting tips(3,4) are coated with carbo nitride coating with less friction serving as an abrasion protective layer. The coating is formed by guiding carbon and nitrogen of a gas body to a reaction chamber in order to form a carbo-nitride layer and by using an improved PVD method of continuously driving ion sources for forming plasma. The coating is applied by the PVD process in that, for creating the carbo-nitride layer, carbon and nitrogen in the form of gas are introduced into the reaction chamber, and one or several ion sources are continued to be operated to form plasma.
