Power tool
As power tools , all tools are designated to be used by an electric drive and thus of a substantial simplification to be provided work performance care. In hand-held, transportable devices, the motor is an integral part of the tool. Important power tools are electric drilling and grinding machines as well as jigsaws and circular saws , but also screwing tools such as cordless screwdrivers are manufactured with electric drives. Power tools are available in wired and wired equipment. Without a direct connection to the power grid, an accumulator is used as an energy source. In this way, cordless tools increase mobility when performing work. Manufacturers offer a wide range of gardening tools and devices in the craft or industrial sector. Actually, one should speak of electromechanical tools, since these tools always consist of an electric drive and a mechanical tool .

history
The history of power tools goes back to 1867. Here, Wilhelm Emil Fein and his brother Carl founded a "workshop for electrical and physical apparatus". The company C. & E. Fein was founded. In 1886 Robert Bosch opened the "Workshop for Precision Mechanics and Electrical Engineering" in Stuttgart. The Allgemeine Elektricitäts-Gesellschaft ( AEG ) presented the first portable and electrically operated drilling machines eight years later. Another three years later, these machines were given a solid metal housing. AEG presented the first drill with pistol grip in 1908, but Black & Decker (founded in 1910 as The Black & Decker Manufacturing Company ) received the patent for it in 1917. Another five years later, an electrically powered circular saw is developed by Edmond Michel. In 1929 the first angle grinder from FLEX - brand name corresponds to the generic name - is presented. In the following years all manufacturers developed new devices and tools: 1932 high-speed multi-function tool Dremel , 1939 first electric hammer from AEG, first jigsaw from Bosch, 1950 electric hand grinder from Metabo.
Industry power tool manufacturer
The industry "Manufacture of hand-held power tools" (electric tools, also power tools) is listed as a sub-area of machine tool construction according to the classification of economic sectors in statistics, but differs significantly from classic machine tool construction in terms of both markets and production.
The power tool industry in Baden-Württemberg, and especially in the Stuttgart region, has a unique concentration in Germany. Almost 40% of the world market share is provided by companies such as AEG Electric Tools (Winnenden), Baier (Asperg), Bosch (Leinfelden, Murrhardt), Fein (Stuttgart, Schwäbisch Gmünd), Festool (Wendlingen, Neidlingen), Flex (Steinheim), Metabo ( Nürtingen), REMS (Waiblingen) realized. If one also considers other elements of the value chain, such as For example, the interdependence of these power tool manufacturers with important suppliers in Baden-Württemberg, such as switchgear manufacturers, clamping tool manufacturers and gear manufacturers, at least approaches for a “ cluster power tools Baden-Württemberg” can be spoken of.
However, this value chain is under strong globalization pressure. Up until the beginning of 2006, the market for power tools was characterized by two trends: on the one hand, a shrinking domestic market, and on the other, increasing sales volumes worldwide with a simultaneous decrease in sales value. The manufacturers of power tools reacted to this with extensive restructuring measures that did not stop at job cuts and production relocations. In contrast, the industry has been developing very positively since the spring of 2006; there is a downright boom in power tools, which is evident in both volume and net sales. All in all, however, the competition among manufacturers is still characterized by fierce price wars and can be characterized as global predatory competition. From the perspective of the German manufacturers, the question of international competitiveness will be decided in a very similar way to classic mechanical engineering based on innovation leadership and production efficiency. The increasing demand for battery-operated devices represents a challenge and at the same time an opportunity. While US-American manufacturers as well as Japanese mostly use outdated and environmentally harmful NiCd batteries, German manufacturers are almost without exception represented on the market with the latest Li-Ion battery technology.
