Kennametal KC9125
KC9125 is a Kennametal carbide turning insert grade placed at the ISO P20 application position (steel) in manufacturer-published grade comparison charts. The charts list 10 comparable grades from 5 brands at the same position. Sharing an ISO position is a chart placement, not a claim the grades are interchangeable — verify on a sample part before switching.

4 of the 10 placements are independently confirmed by two or more charts. None of this is a metallurgical equivalence claim: chipbreaker geometry, coating and edge preparation differ between brands. The safe path is always a sample-part test.
