GRADE CHART · ISCAR

ISCAR Carbide Grade Chart

This table lists the ISO application class each ISCAR grade is positioned at, per manufacturer-published grade comparison charts in the grade_equivalence reference database. Positioning at the same ISO class does not mean grades are interchangeable between manufacturers — substrate, coating and edge preparation still differ, even at the same class.
