Tungaloy AH630
AH630 is a Tungaloy carbide turning insert grade placed at the ISO M20 and S20 application position (stainless steel) in manufacturer-published grade comparison charts. The charts list 25 comparable grades from 9 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.
