what's the name of the drill bit....

...that can be used, to remove a screw with a damaged head?

I am trying to take up the decking in the garden, but some of the screws will not come out as the head is damaged.

I've been trying to find it in B&Q, but they seem to be next to useless and had no idea what i wanted.

Thanks

Do you mean a countersink bit? If you're trying to remove just the screw head then that's what it's called.

countersink bit is for getting the head of the screw to sit below the surface of the material

what the op wants is a damaged screw extractor

Not necessarily, if it's into wood then it's easier to remove the head then grip the shank and remove the remainder.

http://en.wikipedia.org/wiki/Countersink- my understanding of countersinking, is it a different bit you are refering to?
Surely a contersink bit for wood would be too soft for the metal of a screw head

I'd use an ordinary steel countersink bit to remove the head.

Something like this will do

How would that work?
I thought that the purpose of this bit is to allow the screw to be sunken into the wood.

Although i already have one of these in the garage, so i will give it a go; as it might save me £10.
