How can I Run a 230V 50hz tool on 100V 60hz
Most motors will run on 50 &amp; 60 Hz so you need a step up transformer to run a 230v tool on 100.
Here is step up/down. You will need one large enough to handle the wattage of your drilling machine. When I searched step up transformer there were some as high as 2000W. These get more expensive as the wattage increases. If you go with a step up transformer make sure to get a larger one than you need by at least 10% and 20-30% if you will be using it for long periods of time as they get hot when over loaded.
