Seco Milling Insert Grades

The black oval circle areas in the chart indicate an inserts main ISO application groups.
The white oval circle area in the chart indicate an inserts other complementary ISO application groups.

* You can increase your toollife by comparing grades. Lower number = Hard grades for wear resistance, Higher number = Tough grades for chipping resistance)

So P10 is harder than P20 with better wear resistance, P30 is tougher than P20 with better chipping/fracture resistance

Black oval = Main application
