Carbide Grade Selection 331

Carbide Grade Selection describes the different carbide tool grades and explains how to select the proper grade for a cutting operation. Carbide grades are classified by two systems. The ANSI C-system lists grades of C1 through C8. The ISO classification system designates carbide grades as P, M, and K, followed by a number that further describes the qualities of the carbide. Carbide grade is often dependent on the type of metal used: tungsten, titanium, or tantalum. Grades have different levels of hardness, toughness, and wear resistance. Coating carbide tools can increase wear resistance and part quality. Selecting the correct carbide grade is essential for decreasing manufacturing costs while maximizing tool life, part quality, and production rate. After taking this class, users will be able to identify the different carbide grades and select the proper grade for a particular cutting operation.
