Does it work with Dewalt 90 grinders?

Only if they make a mandrel with a male stud the same that is on any basic grinder, it doesn't look like the 90 has that

What's the grit material? Is it good for metal & stainless steel?

Assorted grits. Not recommended for metal.

My grinders all have a 3/8” arbor. Is this adaptable?

Believe you will need an adapter to convert the 3/8" to 5/8". Have used it on several different brand grinders, but all have the 5/8" spindle.

Can you wet sand with these discs?

Yes, you can wet sand with these discs, and they stay attached to the backing pad and work perfectly. This is a great buy.
