What drill bit is strong enough to drill a screw out from the head of the porsche 944?

WTH!!


Why did the porsche engineers use alien wrench screws for the head of the engine. The last screw that i have stripped and am wondering is there any drill bit out there that wont go dull the second it touches this strong piece of German steel.|||Be careful with easy-outs. Go slowly and carefully. If you break that off in there you'll have a real problem. I recommend sending the part to machine shop to let THEM remove the stripped piece. (If that is possible)|||You want a few different size carbide drills and a center drill. You're better off taking the engine to a machine shop unless you have experience with this sort of thing. If you drill the bolt out and aren't exactly on the center you just trashed your block and need it to be machined anyway. It will cost more to have the shop fix if you eff up than to have them do it in the first place.|||Get a set of easy outs. Typically available in various sizes from auto parts stores or even Sears.





They pull themselves into the head as you turn the bolt counter clockwise to remove it.
