You have to work your way up, not just a pilot hole. And use some kind of lube. Use the slow setting and let the tool do the work. Forcing it isn’t the way. That is how you break a wrist. I drill steel all the time with no problem up to 1/2 holes through around 3/4” thick. Beyond that I would recommend a hougen. 1/4 thick steel should be like butter if you are doing it right.
