Hilti is not as widely known in the power tool segment as Bosch and Makita are leading companies. In the class of multifunctional screwdrivers, the company has only a few basic models, and not all of them are suitable for mass application in the household. But not only the narrow assortment explains the low popularity of the brand. Developers are guided by a professional class, while maintaining the ergonomics inherent in everyday versions. A typical representative of this concept is the Hilti SFC 22-A, which can be considered as a station wagon. It has a sufficient power reserve, a reliable elemental base and a modern set of options. However, the price tags of Hilti products are very solid, so you should familiarize yourself with the practical capabilities of the tool before buying.
