Re: Advice on removing snapped s/s bolts from alu block
I have experience with this. You will have to drill the old bolt out starting with a very small bit.Use titanium bits. For an M6 get 3 bits the largest bit the same size as the bolt. Then get a NAPA helicoil kit. It includes a special size drilland tap. It will be easier than you think, just follow the directions. You thread the helicoil into the new threads and then use a new bolt. Motorcycle mechanics know all about this. Its a very common repair. I have done this and it works.
Easy Outs are crap and don't work!
