The STAHLWERK cordless tools promise maximum power for extra long work sessions. The powerful brushless motors achieve higher efficiency than comparable machines and work almost wear-free. In addition to their low weight, the drill tools are particularly impressive due to their reduced heat generation, longer maintenance intervals and an extremely long service life. Since modern brushless motors do not require mechanical contact to transmit energy, they work without abrasion and therefore have a significantly longer service life. The absence of carbon brushes protects the cordless tools from wear and loss of performance. Another advantage: Compared to conventional motors, the compact brushless motors consume less electricity with the same output power. A powerful and fully compatible 20 V battery system enables the greatest possible flexibility and long operating times. The powerful batteries are suitable for all devices in the STAHLWERK Brushless series with 20 V, such as cordless screwdrivers, rotary impact wrenches, hammer drills, angle grinders, straight grinders, circular and jigsaws, etc. Thanks to the latest lithium-ion technology, neither memory effects nor self-discharge occur. Available in the usual STAHLWERK quality with a 7-year guarantee on the devices and a 2-year guarantee on the batteries.
