C2 and C6 carbide

Most brazed carbide tooling will have the carbide grade marked on the shank of the tool. Carbide inserts can be a totally different matter. Many manufacturers have their own identification system, and there are many grades and sub grades. Added to that the inserts are often found loose and are unmarked and it becomes even more confusing.
