Questions about R390-170420-PM

Is VPOINT R390-170420-PM interchangeable with the equivalent insert from other manufacturers?

VPOINT R390-170420-PM follows the same ISO 1832 designation and geometry as the established milling inserts inserts it is positioned against, so it seats in the same holder for most operations.

Can VPOINT supply R390-170420-PM in a custom grade or coating?

What is the minimum order quantity for R390-170420-PM?
