Questions about door hinges.

I'm not veryexperienced in carpentry. Rebuilding my tear is the most difficult thing Iv'e done. The first time around I just fixed it up so I could get to the IRG. No way would it survive in the rain. I also couldnt put propper locks on the doors. The first project is the doors. Loved the curves but making them match the body is beyond my skills. Reframed doorway as a rectangle. Nice and square now. Made new doors, square, flat and best of all, they fit perfectly.
I'm ready for the hinges. Got aluminum that need to be drilled. I'm hiding the door side under the trim. Can I tuck the body side between the door and body. Got stainless steel wood screws. They are flat headed but need a tapered hole. What kind of bit do I need to drill the hinge. I have bits for wood that countersink wood screw heads. Do I need a special metal bit. I don't want to ruin the ones I have.
