You can use 240 volts. It is available in USA. The frequency is 60hz not 50hz so they might run a bit faster. Otherwise you need a transformer with a high enough current rating to run your tools.

The "standard" residential electrical service in the USA is a 3-wire, 220/110 volt 60-cycle system which means you can connect circuits for either 220 volt or 110 volt operation. As for the performance of a 240 volt 50-cycle motor operating on a 220 volt 60-cycle circuit, much depends on the type of motor. If the motor operates without brushes it's an induction motor. If it's a brush-type then it's a "universal" motor that operates on both D.C. and A.C.---Good Luck!!!

50 Hz motors will operate just fine on 60 Hz. They will run faster. The converse is NOT true. A 60 Hz motor on 50 Hz will overheat due to the iron core saturating.
