Hey every 1 Im sorta going crazy here but hopefully some of your ideas can help me out .

Im working on my 88 gmc k2500
I dropped the transmission and had to remove the ypipe to get the flywheel plate off

any ways I broke all the studs in the manifolds even tho i warmed them up real good

I tryed easy outs and they broke
I broke 3 drill bits tonight

Im wondering whats a good brand for drill bits ?
What im planning to do is drill all 6 studs out
then bolt them up with bolts and nuts with the springs in between the flange like it was factory

I have a picture of one of the manifolds but its sorta bad quality sorry


I was originally going to cut the ypipe with a sawzal then weld it
but i went the other route and regretted it

 

cobalt bits

Kobalt is Lowes brand name.Cobalt is a type of alloy...extremely tough

You can buy Kobalt brand Cobalt made drill bits.

 

alrighty i guess ill try those

hopefully i can drill all 6 of them with no problems =/

 

Last time i purchased a cobalt 1/2' bit. It cost me $9.00 for 1 bit.

Ive learned the hard way with exhaust bolts etc to cut pipe and not touch the bolts. you can always reweld pipe.

 

yea i wanted to do it that way but my dad wanted to it that way

sometimes i need to learn not to listen to him =P

i could of always weld it with the mig once the truck went home...... sigh

 

If you could weld cast,you'd be set. Last time i welded cast it cracked in 3 days..

 

we use nickle rods to weld cast smaw stick weld anytime we break cast parts holds up real nice and we use irwin drill bits and the cobalt is by far the best bit for drilling hardened steel stainless should eat right through a grade 8 bolt dang geo i just noticed your dot is green again congrats lol

 

Haha. for how long? :P

 

yea its to late to weld any thing =P Im going to have to buy a good set of bits ....

and thank you

I hate you ...... joking =P

 

today i picked up some cobalt bits and drilled out one manifold

they work real good

tomorrow imma be drilling out the driver side one and geting ready to put the trans back in
