The upper body encases a battery and a motor powered by the battery. The upper body has a plurality of teardrop-shaped sections interconnected by a plurality of ridges. The plurality of ridges bulge outwardly beyond the teardrop-shaped sections and create an enhanced gripping surface on the upper body of the palm grip. The palm grip has an axial opening within the upper body and stop for receiving a shaft. The shaft is rotatably mounted within the axial opening and driven by the motor. The shaft is compressible within the axial opening for activating the motor and actuation of the shaft. The palm grip is positioned within one hand of a user for use on torquing an item.
