There's a whole variety of carbide matrices/coatings used for insert-tooling for machining. They change the binder and coating to alter the properties a bit. TiC (titanium carbide), Ti(C)N (titanium carbide-nitride), TiAlN (titanium aluminum nitride), etc. The tend to all be referred to as 'carbide inserts' unless you're distinguishing between each other specifically.

Pretty cool stuff!
