Those aren't.

The usual "cobalt" drills these days have a "cobalt" (sic) coating on
them, giving a bluish rainbow look. They're cheap, Chinese, and made
of a secret alloy of rubber and bananas. No earthly use for anything.

Yeah - I was thinking more about the claimed ability to drill various
substrates. The Bosch drills do work, (limited depending on substrate, very
well on others).

If I were the OP I'd buy the Bosch which has some record of usability before
a random TV ad set.

Cheers
