If you are going to drill wood only, triple hardened, chrome vanadium,
and other cheap drill nonsense is probably OK. If drilling metal is
anywhere in the scheme of things, they will become junk in mere
seconds. Drills labeled HSS (high speed steel) are the minimum
requirement for drilling metal. Spend the money and do it right.
