I'm trying to hang a towel hanger, but with my own anchors. I'm struggling to drill a hole in the steel hardware that gets bolted to the wall:
I'm using a hand drill, running at about 450rpm. I've tried a HSS stepper bit, 1/8" HSS bit, and a 1/4" HSS bit. I've been using soapy water for cooling and lubrication.
My bits were fairly cheap, so I'm going to get a better quality set, but I'm surprised to be making such poor progress.
