If you do this you have two options. Either put a piece of rubber from a balloon, latex glove etc between the screw and the screwdriver. Or use a hacksaw to put a slot in the top of the screw and use a flathead screwdriver.
I got a set, tried to use them twice and they failed both times. In the first try the bolt metal was too hard for the extrator to bite in in any reasonable time drilling and the second time the screw was too soft and the extractor stripped the hole the extractor makes attempting to extract.
Had to do this on a buddies Harley…
Tried the ‘cut a slot’ method for a flathead too…broke the screw head in half trying to take it out. Drilled it out, head popped off, and was able to take the shaft out by hand. Those screws are made of play-doh…not metal.
First oil change on a new to him bike but some numbnuts but the crank case cover bolts in like a gorilla…torque spec is 7 ft-lbs(9.5 Nm). That’s like a quarter turn past finger tight. It just needs to compress the seal so oil doesn’t spill out.

am i the only person with a set of screw extractor bits?
I never even knew it was a thing. I’m assuming most people don’t have them.

Another option for smaller screws is just to drill out the head, it will let go.
