At 82 HRC, give or take, tungsten carbide is much harder than cobalt or HSS. This is carbide's only Achilles' heel—where cobalt will flex a fair amount in the face of radial cutting forces, carbide will in many cases shatter. This means that proper alignment is critical for tool life and hole accuracy (which is true of any drilling ...
