Hello...

We are using Sandvik round inserts for profiling. The insert in question is N123H2-0500-RM, specifications say that the diameter should be 5 millimeters. However, when measured using a micrometer, I get a diameter of 5.06 millimeters. The difference seems a bit large, is this kind of deviation acceptable? Or is the insert designed so that under normal cutting conditions the insert "acts" as if its diameter was 5 millimeters?

Thanks for your answer!
