Located in the heart of  the Jura mountains and plains, Diager has a strong industrial history. For over 55 years we have been designing and manufacturing tools for the most demanding professional clients. We supply tools in France and in over 70 other countries. On the international market, Diager has created an extensive network to provide a high-level of service to its most far-reaching customers.

Diager’s key values; savoir-faire, certified high-quality, customer satisfaction and forward vision. Our focus;  innovation, adapting to new materials and increasing performance for end-users.

Diager started off as a group of determined individuals, proud to share expertise and new developments with its customers. Our aim is to constantly improve our capacities and optimise our ressources.

For over 10 years the environmental impact of our work has been a major concern (ISO 14001 certification since 2000). This has resulted in a number of projects aimed at reducing emissions, limiting consumption and reprocessing industrial waste. We are forever making progress in this area, for example with the introduction at the end of 2009 of The Bilan Carbone® method for measuring green-house gases and an eco-conception policy for each new product. Diager faces the future with a strong focus on sustainable development, relying on expertise, development of human ressources, innovative techniques and true ethical values to meet our challenges.
