The beginnings of our company date back to 1920, when a one-man business was founded, trading in rough diamonds. In 1949, these activities became Haefeli & Co., which began manufacturing precision diamond tools. In 1985, the stock corporation was established which is still being managed by the family, the brothers Peter and Rainer Haefeli (third generation) and Taro Haefeli (fourth generation).

We are ISO 9001:2015 certified. To know more about the company, you can consult our company brochure. However, we prefer to recommend ourselves through the quality of our products.
