How to understand and make the most out of our Grade Tables

  • We use the PMK convention that is used in most of the cutting tool catalogs. (Example P05-15, K25-40, etc.). If you are not familiar with it please read our Detailed Explanation
  • We divide the grades into several "Grade Statuses":
    • Active Main Grades - Are the primary grades of each brand.
    • Active complimentary Grades - These are additional possibilities either older or used for specific situations.
    • You can use the filter above the table to view both or one of them.
    • In addition, we list on the bottom of the page additional older and non-active grades.
