1919 Foundation of the company CARL WALTER as a tool supplier for the mining industry in Wuppertal. From the very beginning, the company focused on high demands and uncompromising quality.

1930 Through constant expansion the company developed into a Europe-wide recognized manufacturer of screwing, mining and special tools in the 1930s.

1943 Directly after the big air raid on Wuppertal, the company relocated from Barmen to Hahnerberg within the city. In the same year the company Walter Werkzeug Österreich was founded in Gröding.

1965 Takeover of the company by the von Zitzewitz family. The acquisition of the Robert Kremer drop forge expanded the production possibilities.

1973 Carl Walter built the most modern electroplating plant in Germany at that time. The development and production of special tools became more and more the focus of the company.

1995 A comprehensive quality management system according to DIN EN ISO 9002 was introduced to meet customer requirements.

2015 Expansion of the production area through the construction of a new 800 sqm production hall. In the same year the torque wrench production moved from Iserlohn to Wuppertal.


With qualified employees, modern machinery and a high vertical range of manufacture, we guarantee a high quality standard "made in Germany".

    In addition to a comprehensive range of 13,000 standard tools, the focus has always been on tools for special tasks under the most difficult conditions. Safety and security - both in use and for the investment made - has always been and still is the focus of our attention.

    We define the standard for special tools through superior technology.

  • Your problem determines the shape.

    We manufacture your special tool from batch size 1 to series production. The tools are designed and manufactured especially for your application and according to your specifications or ideas. Convince yourself with a simple cost-benefit calculation:

    Standard tool

    Maintenance on an industrial motor is done with a standard tool. This works, but it causes recurring costs due to downtime, manpower and material.

    Special tool

    A tool specially designed for this task may cost more than a single maintenance case, but usually pays for itself from the second. Shorter downtimes, less manpower and lower material consumption drastically reduce costs.

  • Carl Walter special tools: as unique as your problem.

    We will solve your problem – without a doubt and worth the price. The construction is carried out according to your concrete specifications or our assessment and analysis. Our superior technology encompasses experienced and innovative engineering knowledge, high-end prototyping, comprehensive manufacturing methods and quality control at the highest level.
