Flex's success is based on innovation. That was the case in 1922, when they developed hand-controlled tools powered by stationary electric motors through flexible shafts. This innovation continued in 1954, when they launched the first high-speed angle grinder, the DL 9. To make our angle grinders even more reliable, effective, and user-friendly, we continued to develop them even to this day. Flex are now synonymous in the detailing industry for their quality and reliabilty.
