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 - These 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.
Walter Older Non-Active Grades
A list of additional older grades that are no longer in the Catalog, or had been replaced with modern generation grades.
