I have been struggling cutting holes in steel studs (actually in the top plate). My first attempt, using a hole saw, burned up the hole saw, and took forever. My second attempt, using a 1 inch standard drill bit, left the hole too small and nowhere near round.
In both cases, I ended up using a hammer and dolly to flatten out the sheet metal so that I could put a grommet in the hole. Not fun to be struggling drilling over your head.
Got to be a better way. Luckily I may not need to drill any more, but not sure. Do I need to buy a punch?
I think that these steel top plates are probably around 22 ga galvanized steel.
