A 120V drill from North America will
not work properly on a 110V power supply in Europe. While the voltage difference is small, it is enough to cause the drill to run slower and with less power. In addition, the drill may overheat and eventually damage the motor.
If you want to use a 120V drill in Europe, you will need to use a voltage converter to step down the voltage from 230V to 120V. This will ensure that the drill receives the correct voltage and runs properly.
