Snapped drill bit

Nice thought Mr Boyd I've seen worse reality TV.

Well the dremell & grinders didn't work, neither did the Titanium drill bit. I think I'm screwed until I can get the head off and get professional help.

What went wrong Pat, the diamond tipped bits should have cut the old drill ok? was it access to the job maybe? please let us know.

Think the problem was access to the drill bit itself. The only part of the grinding tool making contact was the very tip. This then crumbled away leaving the metal shank to rub against the snapped drill bit. Did try the blunter tools, but they didn't touch the drill bit. I'm starting to think all the attempts to drill it out might have tempered it further. Next plan is a head off job

Probably quicker to swap the head for now. If it's running leave it and get a s/h head then change them over. Get yours machined and then swap back and e bay the replacement.

Once I have the SRX back on the road you are welcome to use the SV for a couple of weeks whilst you fix the XT.

Steer well clear of "Easyouts", once the little b****r snaps you've turned a very difficult problem into a damn' near impossible one.

Judging by how tough whatever is in the bottom of the hole is, it might well be an 'easyout'!

If its still in there,

My two bobs worth.

Blow the swarf and other crap out of the flutes with compressed air @ 10 bar. Then drill down to the bit with a bigger drill to open up the hole a bit if its only 10 mm down and then get some sort of two pronged thing, as previously suggested and twist ,wobble or tug on the bit.The drill bit is only stuck on the swarf being cut at the tip and will only need a small amount of movement to loosen it. If friction is a problem use some wd40 type stuff.  What size is the actual drill bit? If its to drill out a 6mm stud,it would probably be 4mm maybe 5 mm or 3.2 mm bit.  Can you drift down and give it a sharp smack with a hammer to push it through the final grippy  bit if it has almost broken through?

For the two prongs,I have used small circlip pliers to remove broken taps and drill bits in the past. If its an easyout down there, chuck out the head

Steal an idea from the two banger trailies and fit  springs to the head and then to the header, till you can get it fixed.

Be careful if you try this.I did it on a broken exhaust stud,got a bit heavy handed and cracked the bit of the head that the stud was stuck into.

Aye - but whilst the bugger is in ther the head is toast - so giving it a good whack will make it no worse.  Adn it can be welded to mend.

As the Heartstart man said to us when we were trying to come up with the technical term for a 'casualty who has a heart beat but is not breathing'...

His term was 'dead', and as he said - you can not do anything to harm a dead man, so doing your best to get them breathing is only steps in the right direction.  The head is toast, do the kind, gentle stuff first, and when that does not work, get brutal.  If you snap the head in two you hav gone from a US head to a US head - but one you will put in the scrap bin rather than coming back time after time  to try and sort some scrap into a head.
