Right, I need to drop some networking and coaxial cables down from the
loft into a bedroom.

Drilling a hole in the ceiling wall plate is easy from the loft side to
pass said cables through.

half way down the wall is a noggin.

I wish to mount the wall socket lower down than this noggin and run the
cables to the wall socket.

I dont really want to cut a hole in the PB to access said noggin to
drill a through hole.

Is there such a thing as a 1.5m m long drill bit extender I can place
between my wood boring bit and the electric drill?

being able to do this would be a time and a making good time saver!

I have used a copper pipe with a serated end to cut through
plasterboard. Not sure if it would cut through a 2" noggin very quickly.

As a last resort, with flux it is possible to solder onto a steel
woodbit and a brass fitting, using a copper or similar pipe as an extension.

Otherwise Tim's suggestion would be the easiest and least mess.
