I "attempted" to drill a simple 1/8 hole in my handbrake bracket to mount a small switch to ground the warning light when the brake is not fully disengaged. 2 Cobalt drill bits later on the drill press and not even a scratch (literally) in the bracket! WTF? Even if it's hardened steel, I still should slowly get through it. Hoping someone can enlighten me regarding the strange forces at work here...

P.S. The one hole was already there. I was simply trying to drill through the other dimple.
