get cobalt bits or something better than the cheap bits you have.

Okay that's happened to me a million times drilling through peoples firewall, first off try not to use the smallest bit but one just a lil bigger than the smallest you got, also when using such a small bit don't put to much pressure on the tip, i've snapped many bits that way, just take your time and it'll go through the firewall...

alright, i'll work with that 2morrow, but what about the factory grommet?, i was using cheap bits when i snapped it at the time, i didn't wanna use my dad's nice ones in case i messed them up or broke them, but 2morrow i will and use a thicker one etc, still tho, hasn't anybody here actually used to factory grommet? if so do u got pics?

i've heard of a couple ppl that used the factory on this site, but i can't think of any names. do a search, cuz i remember a thread where someone posted pics of doing it. might even be in the FAQ, i'm not sure
