Last option is rotary tool again, grind that head clean off. If there's enough exposed shaft after the part removal then turn with vice grips. Hopefully you used brand name Loc-tite.

Otherwise its screw extract time. I suggest Micro-grabits. Only reliable option IME.

As long as it has a massive IKEA logo embossed (or with filigree) on there somewhere, you have my vote.

I have one of those.

It's labeled "screw it."

bro, they should be sending me metric drill bits instead. Those fucking drywall anchors they send are always in metric and I can never find my metric drill set.

I've got several of those little bastards. I feel the same way.

I have so many high quality hex wrenches now from work. I do not want the cheap ones, but I still feel bad throwing them away.

Invest in good quality tools. Any tool that comes in a ziplock bag usual sucks

That's when you'll discover you need them.

I have even more than that. We regularly replace furniture at work and I end up with so many cheap tools. Once a year I put them in a box, hang a free take one sign and place it out front. It takes a day or two but they leave. Most likely it in their glove box in the car. They are not however in my office anymore.

Also get either a 90 degree attachment or a right angle drill. Good for those spots when even an impact, or even sub compact impact, drill is just too big.
