Yep, the AR Warner stuff will definitely get you started. The W does not stand for warner. Each letter and number means something pertaining to size, shape, radius, etc. Hopefully the chart I post below will answer a ton.
As for carbide, I dont see any reason you can't use it taken its the correct insert. I use AR HSS inserts on a few of my USA indexable toolbit holders. I took the insert and toolbit over to AR Warner and he matched me up with a few HSS bits.
