USER GUIDE
THREAD TURNING Selecting a grade is strongly connected with the cutting geometry of a tool and other factors. The following

Tool Material
grade
• which cutting tool grade is most suitable for threading?

tables show the correct choice: they visualize a grade position in the field of application in accordance
with standard ISO 513 and characterize the grade properties compared with other grades.
The tables provide summary data about grade application in coordinates of classification
numbers from standard ISO 513 and availability of each grade per threading family.
There are main and complementary grades. The main grades are more popular in machining a considered class of
engineering materials, but in specific cases the complementary grades can be effective as well. In situations when a
product produced from a main grade is not available, a complementary grade provides an acceptable alternative.
