By following this rule you could easily end up with a tool that lasts forever but strips out all your screw heads.

[MarkusQ]

Replace "breaks" with "fails to work as intended" then.

A tool that doesn't break but does smell like a refinery or damages nearby electronics when used, gets strangely hot or inexplicably changes shape when idle, etc. should still be replaced.

I don't think that is how screws work. I really have a hard time seeing how the drill makes a difference with that. The bit you use, sure. How you use the drill, sure. Maybe if the drill has a completely messed up clutch maybe, but then the tool is not functional and you should return it.

I don't think anyone is asking you to stupidly follow the advice off a cliff. You're welcome to call "stripping all your screw heads" broken and take appropriate action.

I don't follow this example. Isn't stripping screw heads a skills issue? How does a tool help/hurt with that?

[everybodyknows]

Better machining on a Phillips tip really does help.

[skeeter2020]

that's not an example of a tool that works, though.
