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?
Be careful with the screw, going too far in drilling it out might take the head off entirely.
If that happens you might be able to lift the wood off it, and come at it with pliers, but if the thread are in the board, that could get very… awkward.
