FLEX-Elektrowerkzeuge GmbH is a German producer of high end power tools with headquarters in Steinheim. After producing flexible shaft grinders since 1922, FLEX invented the "Flexe" or angle grinder in 1954. The company created a partnership with American tool producer Porter Cable, until Pentair sold its power tool division to Black & Decker in 2004. Black & Decker divested itself of FLEX tools and it is now an independent company.
In North America, FLEX sell mainly metalworking (grinders and polishers) and masonry power tools, but in Europe it also makes and sells woodworking tools.
