Can you use these on a angle driver?

I suppose you could with the right adaptor but I think they’re better suited for use on an angle grinder with higher rpms.

¿ Is this a good to grind cast aluminum ?

It works well if you use a cutting wax to keep the aluminum from clumping or clogging. Cut-ez is a good one.

Are any of the resin discs available with a5/8 inch hole for a 5/8" arbor?

Since a 5/8" arbor is smaller than the 7/8" hole, these discs can fit over the 5/8" arbor and fasten with the locking nut of your grinder. In other words, you will be able to use these discs even with a grinder that has a 5/8" diameter arbor.

How do these work for grinding welds?

These work great for metal and wood. I’ve used them on steel welds, these last longer than any disc I’ve ever used. I highly recommend them.
