It is widely used in metal manufacturing because of its ability to resist wear over conventional high speed steels, allowing for shorter cycle times in production environments due to higher cutting speeds or from the increase in time between tool changes. M35 is also less prone to chipping when used for interrupted cuts. This step drill also has titanium coating.
