    I need to get a good drill bit that will go through some serious metal. These they sell around here just aren't cutting it. Anybody know where I can order one online?

    What kind of metal dictates the kind of bit, what are you drilling through?

    We just lifted my friends Jeep Cherokee and have to drill a hole with a 21/64 bit in the transfer case output shaft. The one they sent with the kit is worthless.

    I'd go with an 8% Cobalt bit due to the hardened steel that your drilling, best bet would be a solid carbide bit for the hardened steel, it should be good up to RC41.

    But only in a press (better yet a mill) for the carbide or it will likely shatter before you get far.

    Mind sharing why you had to modify the output shaft? I plan on lifting my Cherokee this summer and just was curious what I'm going to run into.

    I am by no means an expert but this is what I have been reading. Stock Jeeps have a slip yoke style output shaft at the rear driveline. To ensure smooth and durable driveline operation, convert to a fixed yoke output and install a CV driveshaft. They recommend this for anything over a 3.5" lift. You can pretty much buy 2 kits. A complete unit for around $300 plus a new drive shaft or the kit my friend got. It is like $180 plus drive shaft. You have to cut the output shat and drill a hole in order to bolt on a new mounting bracket. This is why he needs a good bit. If you have to have this defintly spend the extra cash and get the complete kit.

    So are you drilling into the end of it or through the side of it? If drillin into the end, it shouldn't be threw hardened so won't be quite as hard as drilling in through the side. Cobalt bit should take care of it. And a real Cobalt bit, not the ones at the hardware store that are Cobalt brand /forums/images/graemlins/rolleyes.gif /forums/images/graemlins/rotfl.gif
