Milling Grades - Understanding the Nomenclature

Newly launched grades follow a straight logic to understand the characteristics and suitable working ranges right away.

Before you dive into the strength and the alignment of our Seco milling grades, understand the nomenclature involved.

Newly launched grades follow a simple nomenclature format that allows you to quickly understand grade characteristics and suitable working ranges.

For historic reasons, many grades do not adopt the new nomenclature. These legacy grades will be updated as new generations launch.

All milling grades begin with the letter M to indicate that they are “milling grades.” The same logic applies across other Seco technologies. For example, the T in TP1501 indicates a “turning grade” and the D in DS2050 indicates a "drilling grade."
The second letter highlights the major material coverage of the grade and its peak performance area. For example, the letter P indicates the steel material group.
The third and fourth character/number indicate the application range and is important when optimizing the wear pattern of your application. For example, MP1501 and MP2501 are two strong steel milling grades. They show that MP1501 can be an optimization of MP2501 when you need a more wear-resistant grade.
5 and 0 indicate the applied coating type. MP25-0-1 stands for CVD coating, while MP20-5-0 indicates a PVD-coated grade.
The last number covers the generation of the grade. For example, MP2500 was updated and replaced by MP2501 in 2019 and provided higher wear resistance and toughness for increased performance and cost efficiency.
