Ive been having some trouble lately with a broken bolt in my intake manifold.
Its one of the ones that hold the thermostat housing on my 85'corvette with all the TPI junk in the way.
Ive tried just about every easy out known to man, none of them have worked. Its broken down flush with the manifold, and I can't get vise grips on it or thread a nut onto it, and I don't have a mig welder to weld a nut to it, and the intake is aluminum so I can't heat it up without warping it.

Ive been looking at old threads on here about how to get the bolts out. Only thing I haven't tried is the left hand drill bits. Does anyone know where I can get them?
Ive tried both sears and harbor freight, but all I got was employees looking at my like I was retarded or something and they point me to the drill bit section.

Seems like Sears should have them.

Might want to check the Craftsman web site (its down right now for maintenance) once its back up. If you can find it there, you can get the part numbers and take them to the store.

If you have a Sears Hardware store nearby, those are usually stocked with more knowledgeable staff. I've found the regular Sears stores to be a crapshoot when it comes to finding someone that knows what they're doing in the tool section.

Or do a Google search - there are plenty of places that have them online if you don't mind waiting.

Grizzley Tool have them, I think. We have a set in the shop so I know they are available.

Being in aluminum, you will have a tough time geeting it out with a reverse drill bit or an easy out. Oxidation is not your friends.....Your best bet is to drill it out. make sure you hit centre......

Phone the SNAP ON TOOLS guy in your area,they're everywhere,they all have them.

Like poncho says,it may be real tough in aluminum.
Drill a 3/16 pilot hole the full length of the bolt being very careful to stay as close to center as possible,then buy a helicoil kit,use the specified dril bit and install coil,make sure to use loctite.

I bought a 5 peice set of them for 8 bucks at HF, there called screw extractors, you probably confused them by calling them left hand drill bits.

You can get left hand drill bits... I have a Complete set of them. The left handers usually have a red groove in the shank so you won't get them mixed up with your regular drill bits. I got mine from the Snap-On man. They also have a good set of broken bolt extractors too to use with your drill.

Thanks guys, I figured that would have to drill it out. Ive been at it for a good while, and the bolt is apparently hardened since its taking forever to even put a dent in it with a drill bit.
I'll stop by Harbor freight again tomorow and see if I can try and find anything again.
And I just realized I called typed in left hand drill bits not thinking about it. I guess I should typed in reverse drill bits, I might as well have asked for left hand screwdrivers to

Actually, a left-hand drill bit is EXACTLY what you wanted to ask for. Next time check with McMaster Carr:

I got my left hand drill bits at the local Car Quest store in our little stupid town. You might check your local parts houses. They sre probably a better drill bit then what you will buy at H-F
