Trying to remove wood screws from a panel door, I have sheared two of them flush with the surface behind the door handle.

They are of the hardened type, 3.2mm diameter and there is 20mm stuck in the wood. Any suggestions on how to remove the screws please?

My thought at the moment is to make a core drill that will just pass over the screw and OD about 4.5 - 5.0mm. When deep enough, i will try and get long nose pliers on the end and try and break off the peg. Afterwards I will fill the hole with a dowel.

Sounds like the best idea to me yes

A suitably sized piece of tube (ID just big enough to fit over the screw so it guides it) with teeth filed on the end should suffice.

use a soldering iron to apply significant heat to the top of the screw once you have dug out enough surrounding wood to allow the pliers to get a grip - should break any grip in the wood

Don’t forget to make crossgrain dowels to give the screws something to grip!

Job done!

Followed G.Cowboy's suggestion of using a piece of tube - stainless in my case - and just filed 3 teeth on the end. Coped OK with the soft wood.

I used a normal piece of dowel to fill the (6mm) hole and the screw gripped just fine.
