Assuming a drill of that age is metal-cased, I wouldn't want to use it
on 230v, not worth the risk, if the handle goes live, you can't let go.
I would only use metal-cased tools on 'centre-tapped' (55v to Earth)
110v supplies. Otherwise use double-insulated tools, even large
industrial types are made in plastics casings now.

Still not safe enough IMHO, more than 55v to Earth is considered
dangerous by the HSE, IEE Regs. etc. here in the UK.
