It cuts the irons very well, it doesn't cut them crooked even though it is a thin disc like the inox ones, the only disadvantage I would say is that it cuts slowly.

I used it on a variable speed angle grinder, set at 8000 RPM, mounted on a base, and cut 4x4 perfectly at 45 degrees. Very good product, maybe slow for professionals but excellent for amateur use.

It has some issues... it needs improvement.
I continue to use the old discs for inox.
