Well I did a stupid.

No, I cant stress enough, don't skimp on a bit, if it breaks on you, you'll be in a situation where now you are drilling hardened steel.

Ask them for a norseman bit, they usually have a display case with individual sizes at the front desk. Should be under $10, probably closer to $5-6.

Our Fastenal stocks Cobalt in LH drill bits. Around $10 ea under 1/4". He can order in Norseman.

dont skrimp on drills used for this kinda application and try to keep plenty of cutting lube in there with it. IE drill a little remove add lube, drill a little, add lube, if you have an old school oiling can that might let you oil and drill with out having to stop as much.....

I do. Thanks.

I have one of these drills for tight spaces like that.

It works very well.

Ah ha! My friendly local tool rental shop has these in stock! I didn't realize they're $200 now. I like my Makita saws and sanders. I was looking at 90º adapters for a big drill, but they come with a magnetic hex chuck and you need to adapt to a HSS round bit! Which makes it too long to get in there.

as I mentioned, I'm happy to send you mine. unfortunately, I am out on the road now for a while with a fun trip planed in between. it will be a couple weeks before I get down to our house on the south side of town to snag it.

don't waste your money on an angle adapter. they are all shit in my experience.

you might take a look at your local harbor freight. I think they may have a cheap knock off version of this tool. I wouldn't buy it there if you planned to use it often, but for occasional once a year use, I think it would last a long time.

not quite the same, but I think it may fit your needs

No problem, the Makita is only $25.

Lessee....rent $25, Chicago Electric quality $29..... Maybe both are one-time use!

Haha. Thanks.

Found my old thread -

Conclusion: The drilling didn't get it out. I pulled the top half of the head and both cams, bought a good used exhaust cam, bought HSS 7mm bolts for the cam tool, only snugged them up (it only has to have the teeth engaged with the camshaft), learned how to reset all the VVT, new timing belt and tensioners, replaced PCV assembly, put it all together, it runs fine, 5 years later.

Thank you for the update. I'm sure the volvo enthusiasts will find this page and benefit from it greatly!

Too late now, but if it was super deep, I would buy another bolt, cut the shank & head off, have someone drill a 1/8~5/32 hole through the center of the remaining threaded piece on a lathe, then grind a slot for a flathead across the top.

Use that as a thread-in drill guide, and slowly drill a pilot hole into the broken off piece. After piloted, open it up and try left hand drill bits and/or EZ-outs and see if it wants to come free without Neanderthal levels of force. If it doesn't come out, just keep drilling until you can re-tap it because it's better than dealing with a broken-off EZ-out.
