I've been trying to drill holes in the back control arm for a sway bar for hours and I'm stuck. I've made a small hole through, but the bigger drill bits won't go past halfway. I've tried three different kinds and I think they've been blunted. If anyone has gone through this or has any suggestions it would much appreciated!

try a "unibit" you can get them at most parts stores. it fits in any drill . it starts out a small hole then increases in size as it rips tthrough anything. i use them all the time drilling in frames of vehicles. and they dont dull easily
