A:  Yes

A:  This didn't break in the sheet metal on my truck when drilling through so it's pretty strong.

A:  Pretty sure it's just an electroplate cobalt coating over HSS. No idea what alloy. What I can tell you for sure is that if you center punch your starting point, are generous with the cutting oil, drill at slow speed and pause if the oil starts to smoke, they will drill through commercial grade stainless steel counter tops many times. If you keep these cool and baptize them with lots of cutting oil, they will far outlast plain HSS, "black oxide" or "titanium nitride" bits. If you let them overheat and neglect the cutting oil, they'll die before you are a 1/4" through mild steel.
