Einleitung
Eine versenkte Flachkopfschraube mit Inbus ließ sich nicht mehr ausdrehen. Der Inbusschlüssel griff nicht mehr und mit einer Zange war der Senkkopf nicht zu fassen. Es war eine große Schraube, deswegen war ein Ausbohren schwierig.
Werkzeuge
-
-
Schneide einen Schlitz in den Kopf.
-
Setze einen Flachschraubendreher am Schlitz an und hämmere leicht dagegen, so dass sich die Schraube gegen den Uhrzeigersinn lockert.
-
Drehe sie dann ganz heraus.

Use the same technique for Philips or crosshead screws.
Use a grinding / cutting disk, not a saw blade. Apply the rotating cutting disk gently, do not force or it will break.
If this is a toughened steel or stainless steel bolt (much tougher), it will be best to use a reinforced cutting disk.
Use a dusk mask to avoid breathing the dusk from the disk !
(No, I don't usually, but I should !)

While this works it is very difficult to not ruin the material around the bolt.
What I do is use a torx bit. size one up that is slightly larger then the hole and then firmly tap it in. atttach your drive handle a turn slowly while pushing down. this will normally break it free.
Also before your get to this point try putting your allen key in the hole and smack it with a hammer. sometimes the force of the hit will cause the metal to "break" enough that the allen screw wont strip.
There are also specifically designed screw extractors made for this. These tools are generally two-sided: one side is used to drill the hole, while the other is inserted to extract. If the process works, the surrounding area is undamaged.
Use another Allen bolt to weld over it and then you can easily remove the Allen bolt with the help of Allen key
How do you cut a slot in the stripped steel screw head which is half an inch inside the faucet handle and access hole is only 1/4 inch ?
