Default Bit to drill out exhaust bolt

ok so i put my stock muffler back on like 6 months ago but in the process i snapped one of the bolts, its now stuck in the thread, im returning the car to stock and fixing a couple things i wanna make the car in as best shape as possble before i sell

so now im looking for a bit to dril out the bolt i was hoping someone has had some expierence with this and could recomend one, i went to lowes and bought a couple bits and they kinda work a little bit but there just kinda scratching it and ****** it up and not drilling threw it

also iv only got a 12volt cordless is it because the drill doesnt have enough power

anyway and suggestions to get this bolt out whould be really helpfull


thank you for any and all help

the bolt size should be listed in the helms - and you'll need a tough drill bit - carbide, probably be $10 or so.

i researched this because i had the same probelem only with a rusted bolt. i soaked it in WD40 and then heat it with a butane torch. then drilled a small hole through the center. then used an easy out an dafter the soaking and het it broke loose, i hope this helps. i did this to save me the head ache and time to hellicoil the the threads.

thanks alot guys for the help


its where the b pipe and the muffler meet, on the b pipe side there is that nut thats welded to the flange, i snapped off the bolt inside that, the bolt is only in the nut it doesnt stick out

im dropping the trans in a couple days to get some work done, and i will take the whole exhaust off and drill the ***** out of it, i think it was also do to the limited space, i could never get the drill straght

so well see in a couple days

thanks again

Snap the nut off the other side, pop the remainder of the bolt out, and then get a nut+bolt+washers to replace it from the hardware store.

You have to break it off because it is welded on.

put a socket on the side where the welded on nut is and snap it off the flange and install a nut in its place

No idea if that'll work here, but I inadvertently tried that on a rear suspension piece, and broke a socket and extension...without breaking the nut free.
