I'm going to disagree with you here, to some extent. "A carbide tipped
drill ain't sharp?" Um, no correlation there. A drill is either sharp or
it's not, has nothing to do with whether it's carbide.

I understood Chris to be talking about carbide-tipped masonry bits - see
the "concrete drill" in the Subject line up above. Those particular
carbide bits are indeed not sharp, even when new.

And carbide
cutters are certainly appropriate for cutting steel, particularly
hardened steel, where "high speed steel" drills certainly won't make a
dent.

While you're talking about carbide drills intended for use in steel and
other tough substances. Different thing entirely.

Masonry bits? No comment.

Yeah, but that's what the thread started out discussing.
