Not only does carbide provide cutting speeds at least four to eight times that of cobalt, but far higher feedrates as well.
And because carbide drills also support a feature unavailable with their cobalt cousins—coolant through-the-tool—there's no need to peck.
So while carbide drill bits are very hard, and can cut through some of the most difficult materials, they're also brittle and can break if not used properly
