You'll break them.

It doesn't matter how many drills in the package, they're a random
size, so good luck getting the ones you want to use.

If you really don't want to buy and break carbide bits by drilling by
hand, then a cheap HF drill press (40 USD or so where available and on
sale) would work.  Not wonderful, but it would work.  You could either
use the carbide bits or just go and buy regular hss bits (Internet,
they're available), which don't last long, but then again, don't break
and are somewhat flexible.

I use a dremel tool on a stand, and can second the comment about the
runout of the collets.  May end up trying a proxxon tool myself.
