Removing screws with ruined screw heads or no head

[Keitai]

Couldn't get grips on these rusted screwheads, so I used these universal things (in picture). Just sitting there drilling in for ages then put drill in reverse for a bit. They came out eventually but might just have been the vibrations. Tried different sizes too How do people remove screws when head's totally gone?

Search the forum, been done to death, resurrected several times and done to death again. Do you own a shed? If so do you want to have power in said shed?

BTW, you used the extactors incorrectly. Not that they're much cop used correctly.

None of your business what I'm bodging now. My central locking if you must know.

Gutter vac. I'm changing the outlet

I see.....its the inside of a wet vac.
I think I would have ground off those screws and fitted new nuts and bolts, but no matter it’s done now.

I've got screws out with worse heads than them simply by using the correct screwdriver.
For future reference, @Keit, you are supposed to use a twist drill to drill a hole into the head of the screw/bolt that you want to remove before using the extractors anti-clockwise.

When you say twist drill bit, do u mean what's in the image? I thought these were called metal bits!

Maybe used metal blade on reciprocating saw or angle grinder

They look similar to the ones I've got, you use the other end of the bit (not the spiralled end) to cut a suitable hole for the spiralled end, you do this with the drill in reverse, slow speed medium pressure.

Yes, they are called twist drills or HSS Twist Drills, but not those cheap things. £6.99 for 13 different sized drills is far to cheap to be decent quality. They may get you through timber a number of times but once you start using them on any type of steel, even mild steel, they will soon burn out and become blunt. You should by a decent set from a well known brand such as Bosch which are a better quality and will last longer.

Those ones in the picture appear to have a square shank to fit in a tap wrench.

Drill put hole so the extractor fits tightly then put in reverse I guess
