Query: 1/8 bit broke in half after first use

These bits aren't 'super hard' as the name suggests. My 1/8" drill bit broke after the first use..I have used the other, larger drill bits in drywall and they have been fine so far. It's a good cheap set that can get little jobs done (like putting up wall shelves). Def not heavy duty.
