Hit metal when drilling into a wall. What is it?

Hitting an unknown metal obstruction behind drywall leaves people guessing whether they've struck a safe lintel or accidentally ruined a structural stud. Without knowing what is hidden behind the plasterboard, attempting to continue drilling risks damaging crucial building supports or utility lines.

I measured out from the wall as best I could to translate where to drill up from the basement to hit the wall cavity, but ended up drilling a 1-3/8 hole directly into the bottom end of one of the studs.source ↗

Depth of the hole from the underside of the subfloor is 5-1/4 inches, so it extends about 3 inches into the studsource ↗

However here I hit what sounds like metal.source ↗

What could it be? Can it be just a window lintel that I can safely drill into?source ↗
