A proven high-quality electric battery is installed for reliable work of the tool. Winding made of copper materials is used for maximum useful effect. This winding has a high performance, allowing you to get not only more power, but also the minimum dimensions of the electric motor. To increase the service life of the battery, impregnation is applied with a special lacquer, which increases the electromechanical performance. Protection from mechanical damage is provided by a triple coating varnish, improving the protection of the electric motor.
