A history full of innovation

The first patents of the Duemmmel tool factory were introduced over half a century ago. Driven by his inventive developed ambition, the founding father Paul Duemmel developed products with various application areas in the early fifties. In 1951 the first wind turbine was patented. This allowed for the first time the efficient conversion of wind energy into electricity. The wind turbine stayed on the roof of the first company building for a couple of years and served as an electricity supplier.

After the company had changed from a mechanical workshop into a tool factory, also various other products were patented. These include, for example an oscillation grinding machine. This allowed for the first time to automate the oscillation movement on the grinding machines. From now on even less experienced employees could work with the very effective "pendulum motion" by grinding.

Finally the era of carbide cutting tools began at Paul Duemmel. The first tests in manufacturing and selling tools were even earlier, in the end of the fourties. With the first braced tool patent in 1957 the later specialization of the company, was already clear. Using this tool, it was possible to do inside machining in large diameters. Then, the company Dümmel over the years specialized in the miniature machining. Thus, nowadays it is possible with tools similar nature to machine holes from 0.2 mm diameter.
