"Flexen" comes from FLEX.

Everyone has heard of it. Many use it every day. But very few people know that ' flexen', a common German verb, actually refers back to an invention developed by FLEX, formerly known as Ackermann + Schmitt. But let's start at the beginning:

In 1922, Hermann Ackermann and Hermann Schmitt started a company in Stuttgart-Bad Cannstatt  to produce and sell their new invention: the MS 6 hand-held grinding machine, featuring an electrical motor that drove a flex ible shaft. This feature was the inspiration for this brand-new tool's name: FLEX . And this is the origin of today's brand name and a verb that has become an integral part of everyday German vocabulary: 'flexen' .

In the late 1920s, the engineers succeed in replacing the flexible shaft with an angle gear set. 

In 1935, Ackermann + Schmitt launched a low-speed angle grinder. In 1954, it unveiled the first high-speed angle grinder: the DL 9.

In 1996, Ackermann + Schmitt renamed itself FLEX. In 2006, 'flexen' was officially added to the Duden spelling dictionary

Innovation comes from tradition.

The FLEX still uses the same basic approach, but the tool itself continues to evolve and improve. High-tech plastics replaced cast iron, making the tools considerably lighter. Motor power has increased, but motors have grown smaller and smaller. The motor and gears have become better protected against grinding and cutting dust; the tools have are now more durable, quieter and more ergonomic. The basic idea of the angle grinder proves to be so efficient and successful that it is incorporated into other machines and will continue to drive new innovations.
