I've got a couple of wall lights for use in the bedroom. They're actually
meant to be permanently wired but I need to add flex to them so that I can
plug them into a standard 13A socket. There's a picture here

although these are not the actual fittings I've got, this illustrates the
problem very well.
The bottom of the fitting is curved and I need to drill a hole to take a
rubber grommet that will then allow an entry for some black 3-core 0.5mm
flex. I've never tried to drill on a curve before - any particular
techniques to it?
TIA
Make sure the fitting is well held, ideally with something solid behind
the thin metal. Make a decent centre punch dent and start with a small
drill that is good and sharp. Then use larger drills. Better still use a
tapered reamer to open up the starter hole.

This won't leave ragged edges.
Can you drill from the inside? If you wander at first it won't show.
