equipment mounting question

[Jay G.]

Ok, here's the situation:
I was trying to mount a siren speaker into the bumper on a 08 Oddysey van. Took the bumper cover off as usual. the metal bumper was SOOOO hard I couldnt drill it. Burned 3 bits out trying to. Anyone run into this? I know they use hardened steel, but i've never run into this before?

ANyone have any ideas or suggestions??

thanks!

jay.....

what size bit did you try to use? Try starting with 1/8" bit with some cutting oil or wd-40 and work up in size slowly.
