These are NOT 8% Cobalt?

Amazon is shipping the 3018002 (5% cobalt) in error and not the 3018002b (8% cobalt) as listed in their product title and description. Wish they would straighten this out.

So is this a cobalt 8% bit (3018002b) or 5% cobalt (3018002)? in product description says 8% but part number says 5%. also is this made in usa?
