Impact driver? As opposed to a drill/driver. They can drive screws like drywall screws with less tendency to slip off. Make sure that whatever you use fits snugly in the screw head. Other than that, a screw extractor like Grab-bit. One end drills a pilot hole, the other (flip it over) used in reverse in your drill/driver, will back it out slowly. What I usually find is that the screw head is buried into the wood below the surface which makes it even harder to remove.
Good luck (you'll need it!)

"Hi everyone,
At a tuning today, the customer pointed out that one key (C3) was sticking. I could see right away that the keyslip was very close, and was surprised that more keys weren't jamming when they were pushed down. They were sticking if any pressure was applied during tuning.
The big problem: the 4 screws would not come out. Unfortunately they are phillips heads, which makes things more difficult.
I got out my trusty soldering iron and applied a hot tip to a screw for 2 minutes, but after the screw cooled down it was still impossible to budge.
I solved the immediate problem by sanding down the one key front, but I'm still worried more may develop the problem and I'd really like to get the keyslip off, especially if the piano needs cleaning or regulation.
This is a large (52" or so) Kawai vertical from 1984. First time I've not been able to remove a keyslip easily. I don't think this one was ever removed.
Any suggestions? Heating up those screws is the only thing I can think of that might work.
Thanks!
