Can't drill into stud

[pompousporcup...]

Just how much of the stud is sticking out? If it's more than 20mm-30mm then you have no reason to drill it

You could cut a thread into it and use two solid nuts worked against each other...or file a hex shape so a 6 sided socket fits snugg over it....

Better yet you could weld a nut on it and use that to remove it as I am doing with the last exhaust manifold stud that wont budge

Post a pic of what you're actually working on as there is, normally, a way around any problem. Without seeing it it's difficult to give advice

Is it a cbr125 exhaust stud by any chance?... Bet it is.

Post a pic to prove me wrong

Seriously, 2 days and 7 pages to remove a stud that you can't even post a picture of.

Today I've been fighting with the studs on my exhaust, 1 came out easily enough:

The other 2 aren't playing fairly at all.

1 out:

The last one:

With the stuck 2 I tried cutting a slot which didn't work, I hammered in a larger allen key which didn't work, today I got tore in to them with the dremmel (type tool) and HSS drill bits and got the heads off, 1 came out fairly easily after that.... the final picture is the last one that is being a pain.... but I've ground 2 sides flat and the puddle is GT85, which I'm going to leave there overnight as I can get a good grip of it, but it isn't budging and eventually the mole grips slip off.

An auto centre punch wouldn't be my tool of choice for marking up a stud.
Ok for smashing side windows of a car or popping the seized float pins from a Mikuni BS carb but I doubt it would make much impression in this case.

While I admire your tenacity I really do think some time at night school learning the basics would be well spent.

What did the course used to be called? EPC2 ?

A centre punch should just be a chunk of steel with a pointy end, applied with a big hammer.

I've attached a picture of a centre punch I've done in a bit of M16 stud I had laying around. If the auto punch is getting that deep, it'll probably be alright.

I can't believe you actually posted a number of pics.

And then, atop that disbelief, I am further stunned by your inability to grasp the concept of showing the bit you're having problems with.

Why on god's green earth are you showing pictures of not-the-thing-i-want-help-with, when you could just as easily show a picture of the thing you're stuck with.

Why are you being such a mong? Are you doing it on purpose, just to wind people up? Is it your fetish? Are you shuffling knuckles every time someone tells you to drill your stud?

I think if you need to watch that video of how to use it....

You shouldn't be attempting it



Which reminds me of the windscreen protector I saw last year with the warning message...

"WARNING : REMOVE BEFORE DRIVING"

Really?????

- Hit it hard enough so it works first time.

If you treat it like a princess - it will move and your 2nd hit will be in the wrong place.

- Use a decent light source underneath so you can see REALLY well what you are doing.

- Don't hit your thumb, it hurts, a lot.

It doesn't matter that it's imperial. I use a 5/16 punch for literally everything. But then again, I know how to use a drill.

Absolutely exquisite. G clamp on the cylinder thingy containing all those ball bearings and my table. The cobalt 3mm bit just bored right through making lovely swirls of grey fluffy stuff-so satisfying gave me OCD- went so beautifully deep in like 1 min.
The auto centre punch was brilliant- it made a large enough dent whereas the proper centre punch was shite- did nothing- maybe because my setup had engine on it side so I had to apply hammer and punch horizontally to horizontal stud.
Rocol auto centre punch drill rocol auto centre punch drill.
I bought another set of screw extractors called Trend Grabit Pro- you don't have to drill nowhere near so deep. After deep hole made tho applied the LH drill half of the Grabit and reamed then was 10 sec job to come out with other half
Thanks everyone!

Edit: Rereading, this is such a sad post. I'm so sorry. I can't believe I just got excited about extracting a fucking stud.
I will post pics of this "victory" and shall swiftly move on to the next installment of the Arcane Adventures!
(New CBR chain and sprocket set- I'm used to bicyles so this should be easy I reckon)
