I am looking to find out if Craftsman Portable Power Tools will work in the Ukraine?

Even if you get a converter the hertz difference still will not work Sorry. The other option would be to buy a power inverter for the car that runs on 12volts and have him plug the charger into that in order to charge the batteries, that way the hertz will not matter. I use this method to charge my batteries while driving to job sites, and it works great.Make sure you get a big enough inverter though. Good luck
