There are lots of dual voltage machines out there (in the US) but they are bigger free-standing machines. (Equipment)
Electricians call everything with a motor a machine. (Lights and heating elements are not)
However, it is not as simple as changing the plug. The internal connections need to be moved too.
The dedicated dovetail machine at my old shop was like that. It came to us as an auction purchase. It was previously used as 120v, but we had a convenient 220v outlet. It has run that way for about 3 years.
The UK thing is different. I think they use some kind of jobsite unit. It is powered by the usual 220(240?) and steps down to 110v. They have to use low-voltage tools on jobsites.
I don't fully understand it? Apparently, professionals, who use tools every day, cannot be trusted to keep from sawing through the cord? Yet at home, the tea kettle on the countertop (worktop to them) runs on 220 (and it's full of water)
Make that make sense.
Regardless of all that, going the other way takes a bit more. You need a step-up transformer, but as far as I understand it, that doesn't come free. You lose some duty-cycle, in the exchange. You can't gain power out of nowhere.
The frequency (Hz) doesn't seem to be an issue, at least with motors. It might run slightly slower (or faster depending on which way) but it doesn't damage the tool. I suppose it could disrupt something with an analog clock? (though there may be internal regulators to solve that too?)
I have been running a UK model TS60, since before they were available in the US (May 2023) They are 110v/50Hz, running on US 120v/60Hz. It has made zero difference, as far as I can tell anyway. I have never used a real NA unit, to see if there is a difference. If it does run faster, it feels fine.
