100 years of FLEX

Proud past, exciting future

Founded in 1922 in the Swabian town of Bad Cannstatt near Stuttgart, the company Ackermann + Schmitt from which the FLEX brand emerged has always been synonymous with an extraordinary enthusiasm for innovation and the ambition to develop even better tools from good ideas.

We are proud of 100 years of inventiveness and a passion for power tools - true proformance.

And we're looking forward to the future even more: always keeping at it, showing full commitment and so celebrating success time and time again. That's what motivates not just our customers but us ourselves, day after day.

Proud past

DL 9 first high-speed angle grinder

The "flexible shaft", which acts as an intermediate piece connecting the drive and the tool, is the origin of the company brand FLEX and became the generic term for the angle grinder. In the early days of the company's history, this was the starting point for numerous product ideas and developments that contributed to the rapid growth of the company. As early as the 1930s, the company headquarters had to be relocated and enlarged several times to meet the increasing demand. Abruptly interrupted by the Second World War and the early death of Hermann Schmitt, the success story was continued in 1946. With 40 employees and the production of scissors and a hand-held grinder, the company quickly picked up speed again. Growth, international expansion and successful new developments were to shape the subsequent decades. The successive expansion of the new company headquarters in Steinheim continued into the 1980s.

With the first high-speed angle grinder, the DL 9, FLEX finally made industrial history in 1954. This key product for the modern brand history was to be followed by many more.

Exciting future

Here's to an exciting future - with yet more innovations for true professionals in the trade.
