broken tap in crank
#11
Most taps are made of carbide, you will not have much luck tring to drill in to it. And to top it off, you will need to use "left hand" drill bits if you are going to try any drilling. Standard drill bits will only twist the tap in deeper if you can get them to bite in to the tap.

the tap is most likely mild tool steel if not carbide. I'm a plumber and have used extractors like the ones your showing me Garis, but like slows2k and dressed2kill said the bits will lose. lol I like the EDM method, learned something new for future referance.thanks.but I've just decided to sell it as is.

If you can get the tap out (I like the nut idea) the threads can be fixed with a Helical thread insert or other types of thread inserts. (Assuming the crank metal is soft enough to drill and tap).

I sold three blocks that needed to be sleeved for 300 + shipping. They were block and griddle only. I sold the cranks sperately.
So if the block is still in goo shape, it may be worth more.

S2Kart I'm aware of this but I don't know what type of tap was used, and it doesn't help that its rusted.
