Features Hitachi's User Vibration Protection (UVP) system that reduces the vibrations from concrete drilling or chiselling with resonance occured by moving a weight in the opposite direction to the movement of the hammer. Reduction of vibration by approximately 33%*1 makes operations more comfortable.
