I've been trying to extract some brass pilot screw out of some aluminum carb bodies. In the process i've broken a #1 twist type easy out off in the head of this brass screw. The head of the screw is about 1/4" down a hole in the body. I can supply a picture if needed. But I'm at a loss as to how to get this tool steel out. Is it possible to drill tool steel, if so what kind of bit can I use? Would it be better to use a diamond bit and a dremel to grind the piece out?
Before trying my extraction i soaked the screw hole with PB oil for 3 weeks, then drilled my pilot hole with the appropriate drill size in a mill then used a hand driver to turn my easy out. I was heating the casting with a small butane torch to help break it free and still it broke the easy out. Any help is appreciated. Thanks
