It may not have enough grip to pull the cutter straight out, but can you get the shaft to go back in to engage with that grubscrew enough that you can get the cutter turning again? If so I'd keep spinning it anticlockwise and try to gradually walk it out.

If that doesn't work, can you show a close up end on shot so we can see what's left of the cutter to try to engage on?

Can you glue something into the cutter to pull it out with? Just put the glue round the sides, you don't want it falling down the hole in the middle.
If you can get a spare cutter handle, you can use a permanent glue like araldite.

expoxy the driver tool into the cutter to block the hole up and then crank the engine - would that blow the cutter out?

Good ideas. Will try.

Haven't tried, but I don't think it would be strong enough - the rawlplug seemed fairly tight.
Would happily sacrifice all my tools at this point!

Luckily have a plastic plug in there so safe.

This seems more likely to work.

Will add these to the list, thanks all.

or find something reasonably soft as a shim and hammer the driver tool into the cutter and as greenv8 said, rotate and ease the cutter out slowly

Would a suitably sized 'easiout' grip enough?
Obviously it needs to be firmly attached to whatever extension is being used on it so it doesn't became another fixture.

The worry with using eaziouts for me would be how brittle they are in case it broke in the process.

Possibly your biggest problem may be that if the grub screw has undone itself enough to let go of the cutter, has it undone itself enough to get jammed against the wall of the injector well.

I mention this because I am surprised that the screw/expanding bolt methods you tried didn't work.

Can you have a look down another & ascertain if there would be a "step" in size between the cutter & the injector nozzle that could be "hooked under" with your expanding bolt method?

A blind bearing puller might do this. You need to have a search around for one with enough reach and thin enough to reach into the cutter body.
In future (if it didn’t already have one) drill a small recess where the grub screw lands on the flame part of the handle. This will help stop this happening, and allow more force to be able to pull it back out, with less risk of the handle pulling out.

I did say araldite. Araldite=epoxy!

Would something like a pair of internal circlip pliers get in there to grip it from the inside.
Failing that the epoxy idea seems a good idea, but pull out , or turn anticlockwise, not turning over the engine, although you might end up with a bigger problem if it wont come out.
it does sound like the grub screw is the problem here, probably come out a bit and jammed it up. i would imagine the tool is hard, so not sure trying to cut into it would work.
Good luck, and let us know how you get on.

Watching a mobile make specialist mechanic using one to remove a broken spark plug, the torque he was using was unbelievable, the sort of leverage and pressures that one would be exerting on a tight hub nut, obviously these weren't cheap tat from the usual auction site.

It's out! Tapped a thread and used a slide hammer.

Does that mean you now have metal swarf inside your intake manifold? Or have I missed something?

There's a little plug in the injector well to block it off.

This happened to me - with exactly the same tool, albeit on an N47 engine.

Well done for getting it out!

is it worth grinding a flat or slight groove on the driver tool, so the grub screw will have something to grip onto should it become loose in the future?

I said the same back up there ^^^^ somewhere.
