So I’ve got some rusty old floor screws that I can’t loosen with a Phillips head (they’re old, so I’m betting it’s not posidrv). The notches are all rusted and it hardly bites at all.
If I drill them out, I know I’m in for a hard time but am I better off going for a really fast rotation or slower?
And should I start with a narrow drill bit and work my way up (historically I’ve broken a few doing this in the past) or just begin at the intended diameter?
Yes, in fact I do work with computers - isn’t it obvious?
Another tool (which I use) is a screw extractor. They come in sets, and are a conical reverse-direction screws.
You drill into the non-moving screw to give the extractor an area to purchase (unless the screw is already pretty gone), put the extractor on a drill/impact driver (the other kind), then run it in reverse until it catches.
When it does, the screw turns backwards with the drill/driver.

Brilliant, thanks
It’ll be interesting to see how far the rust goes
