FLEX traces its origins to Ackermann + Schmitt, founded in Bad Cannstatt near Stuttgart in 1922. The company’s early flexible-shaft drive technology gave rise to the FLEX name and became closely associated with the development of handheld grinding tools.

In 1954 FLEX introduced the DL 9 high-speed angle grinder, a defining product in its modern history. Continued dialogue with professional users has since supported development across metalworking, automotive finishing, renovation, stonework, drywall and other demanding applications.

The current range includes 12V and 18V cordless tools, mains-powered machines and compatible accessories. Products cover grinding, cutting, polishing, sanding, drilling, dust extraction and specialist finishing, with brushless motors and battery platforms used across newer professional systems.
