Use a timesert. If the hole is hogged out too big for the timesert, use a Bigsert. Don't use a helicoil. This is an easy repair.
If you're not comfortable performing it yourself, any machine shop should be able to do it.

I was looing on eBay they have this listed: Glow Plug GLOWPLUG Thread Repair Inserts M12 x 1.25mm Pack of 5 for total cost of about $21. However it is just the inserts not a tool kit.
There is also inserts for other sized glow plugs. There is also several Tool Kits for diffrented sized Glow Plug tread repairs: Glow Plug Cylinder Head Metric Thread Repair Restorer Tap Kit M12 x 1.25, $50+ "Description Professional tool for commercial or occasional use Glow plug Thread repair kit M12 x 1.25 Suitable for repairing the glow plug mounting thread in the cylinder head Fast and effective remedy for damage to cylinder head glow plug threads Unique assortment for the repair of worn or damaged threads Provides absolute firm and gas density seat for many uses This kit ensures a straight thread and new insert provides an efficient fit Essential kit that solves common problems on diesel engine alloy cylinder heads Set includes tools for the precise insertion of threaded inserts into the head and features a unique tap guide system to ensure their correct alignment Essential tool for alloy cylinder heads"

Amazon or other places likely sell similar kits What I see that I like about the kit is that the tools have pilots on them to center the tools in the inner glow plug hole (the part the tip of the glow plug goes through). Having pilots on the tools makes it easier for someone who has never dont it to be successful.

I have used Timesert and can vouch for it. Each size kit comes with the tools needed for that size, the reamer, the bit,the tap and guide and of course the tool to insert the Timesert. It was quite easy to do, although I did not use it on a glow plug hole. I would probably do it without removing the head, you could drill with a shop vac rigged up then put grease on the tap to hold the shavings. I did not hesitate to buy the kit as it was cheaper than letting a shop do it plus I have leftovers in my tool box now if I ever need another fix. And I am a tool addict anyhow.

Generally you can fill the grooves/flutes of drill bits and Taps with grease and that will trap the metal chips in the grease.
However, you need to turn the drill bit slowly so it does not heat up and melt the grease. There is a bunch of Kits to rethread damaged glow plug threads but I would pick the kit that has the pilot rods on the taps and drill/reamer. Personally I have a lot of trouble drilling a hole straight in the direction I want to go and that gets worse if I am at some odd angle or there is little room in it. Also Aluminum can be sort of grabby when you drill into it. The kit with the pilots has a reamer that you turn by hand and do not have to use any power tools. That hand turning allows you a lot of control you would not have with a Drill Motor and Drill Bit. The Glow Plugs seal on an angled shoulder. If the hole and/or threads are off center there is some chance it may not seal. I don't think that is a really big deal as you can get a small Copper Washer and use that between the sealing area and the head to seal. But, it is nice to not have to do that.

i see what you mean... getting that drill hole nice and straight would be critical
http://www.peachparts.com/shopforum/diesel-discussion/235397-om606-glow-plugs-dont-know-whether-laugh-cry-3.html post #42. looks like he's using hand tools for the reaming, the threading and the insertion. don't see what he used to enlarge the original hole in step one.

You could do that with Aluminum but it would of course be slow. But, that does not guarentee it going in straight. There is some youtube viedos on doing the job with various tool kits.

Job done!!!
Decided on taking my chances on fixing it myself with the timesert. Worked perfectly got everything put back together in about two hours total. My helper/the car owner got a picture of me hunched over it checking everything out right before we fired it up about midnight last night

Did you use a Drill Motor or turn the Drill Bit by hand?

I used a battery drill. I wanted to use the hand chuck gripper tool I bought but the drill bit from the timesert kit was too big to fit. The other tools fit in it fine. Drilling it was about the most nerve racking part but access was perfect and i just went slow. No problems.
