Homebrew PCBs

I do not plan to do much through-hole (for this reason I am reluctant in
investing in something pricey/bulky) but I occasionally need to make holes.

I have bought some carbide bits at harborfreigh and I have a dremel; on
the other hand, I've been told those bits can  break easily (well I
think one can break them just by watching them too much, they are so small)

What is the recommended solution?

Thank you!
