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 materialwhat the op wants is a damaged screw extractor

(similar to the link above, think wilkinsons do jml stuff now woolies has gone)
but be warned, these things are hardened steel- if they snap there is little chance of getting the screw out with part of the extractor in place.
The other option is to drill the head off the screw, lift the decking and then either try to remove the screw with locking pliers/ mole grips etc or cut it off flush and re fix in a different position.

Surely a contersink bit for wood would be too soft for the metal of a screw head

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.
A countersink bit will remove all traces of the head allowing the decking to be removed and then you can get a better grip on the shaft with Molies or pipe grips. Yes, the idea is to trash the screw if it's irretrievably damaged.
Before you go down that route though do you have an impact driver? That'll do the trick. You can also use a normal screwdriver to similar effect if it's a good one.

op, this won't remove the screw like the extractor, it removes the top of the screw allowing the wood to be lifted over it but still leaving the body of the screw in place

Offer up a HSS twist drill to the shank of one of the screws you have already removed, then pick the next drill size up.
Load drill into drill chuck and drill in knackered screw head, the head should then fall off when you have drilled down to the shank.
Lift decking board off the remaining screw shank, when shank is exposed take a firm grip with mole grips and unwind screw.
HTH.
