In 1867, Wilhelm Emil Fein founded a company for the manufacture of physical and electrical devices. His son, Emil Fein, invented the first electric hand drill there nearly 30 years later, in 1895. This invention laid the foundation for the highly reliable power tools that Fein continues to manufacture in Germany today and for which the Swabian traditional company is valued in industry and crafts worldwide.
