carbide is really brittle ,i think it would crackWould it be possible to use a small diamond slitting disc and use an impact driver?.

I've tried welding to no avail, The cutter isn't bottomed out , there is a good 20mm under it , Its gone tight because swarf has had nowhere to go and seized up the shankcan you tig a nut on it and wind it back? Im guessing as it bottomed out the teeth have snagged in the aly at the bottom of the hole? lots of heat soaked into the block the differential expansion of ally and TC must be quite big?
(im an expert at sticking steel to tungsten BTW )
I haven't, I will have a go at thatHave you tried tig brazing a nut or bolt to it?
Should braze fine and then you should have something to connect to and try a slide hammer or hollow jack.
Thanks for the offer it's much appreciated but I have some rods , I'll give it a bash tomorrow.If you have tig brazing rods great, if not you could even try some stripped twin and earth cable (what have you got to loose)
I've 2.4 sif no8s and could send you a couple over if no one closer has any.
I think a smaller size would work better though.
A guy I know who had a small business got asked to price for taking 0.2mm out of the bore of some carbide parts. He got a sample, ordered a CBN insert and gave it a go. Piece of cake, machined very easily and he put in his price. Got the job instantly which rang alarm bells with him but what the heck he thought. Got all the order and chucked up the first one and it wouldn't bore, turns out he could only get one part per insert and he had just priced slightly above the cost of an insert so basically he did the whole job, 2 days work if I recall, for free. He wouldn't make that mistake againStefan Gotteswinter has successfully turned carbide tooling with CBN.
Polycrystalline diamondPCD?
I could try it but I only have 3750rpm ish spindle speedPCD tooling can turn carbide but it's expensive and the spindle speed required is crazy.
