In 1941, the company faced the death of one of its founders, Hermann Schmitt, when he was killed in action in Russia.

In 2013, all shares in Flex-Elektrowerkzeuge GmbH were acquired by the Chinese company Chervon Holdings Ltd.[6][8] In North America, FLEX sell mainly metalworking (grinders and polishers) and masonry power tools, but in Europe it also makes and sells woodworking tools.

As of 2019[update], the company employed 250 people and generated a turnover of EUR 81.59 million, with 63.3% of sales attributed to exports.

Following a restructuring of Chervon Holding Ltd., it now operates as an independent company, though it continues to use the Flex brand name, featuring a black and green design.
