In the UK, you can easily buy construction site transformers,
which give you 110V with a centre-trapped earth. This would
be fine for tools up to 3kW, but for anything much more,
you should weigh up carefully if it's going to be cheaper
to replace. You don't say what the power consumption of
your drier and range are.
Induction and synchronous motors will run slower and possibly
hotter. Your drier likely has an induction motor as it
probably operates at only one speed. Hand tools usually have
universal motors which are smaller for the same power output,
and don't care about the mains frequency.
