Tungsten carbide is a compound but the finished
product you refer to as "tungsten carbide _tooling" is better called
cemented tungsten carbide. The cobalt is not in solution but is found
at the interface as a glue (cement).
In practice the cemented carbide tools frequently are a mixture of
carbides cemented with cobalt metal.

Ahh but the question IS; can tungsten carbide tooling (since it is an
intimate "mixture" of tungsten, carbon, and cobalt), be correctly
referred to as metallic or a metal since the finished product has
metallic properties?
