Broken easyout

[tutties]

My son has snapped an easyout in the cylinder head of his integra when trying to remove a broken temperature sender. We’ve tried all of our various drills but none of them will look at it. Do we need to get cobalt or tungsten carbide drills before it will make any impression ?

Thanks everyone for the replies.

I did think of welding a bolt on so tried it on the broken easyout first that wasn't attached to the engine. I used mig with a flux cored wire but the weld didn't take properly to the easyout and i couldnt see how it would work with such a restricted access with the piece still in the head. I hadn't thought of using flat bar with a hole drilled and then welding through the hole..... I think I'll go give that a try next. I think my son originally chose too big an easyout, the part he was trying to remove was already hollow and made of brass (i think,temp sender) and the easyout just pushed through the brass and everything locked up. To answer thinfourth2 we are in Arbroath.
Thanks again for all the replies..... I guess I'm in the garage again today ......
