Swiss Precision
A Swiss family company, that develops and manufactures high-quality sintered diamond grinding tools from a diameter of ø 0.18 mm and upwards. We are known for our outstanding and constant quality, flexibility, short delivery times, close cooperation with our customers and innovative spirit. Based on decades of experience with customers from a wide variety of industries as well as from research and development, we know how a grinding tool has to be designed for a wide variety of grinding tasks.
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 also being managed by the family. Our company is led by Taro Haefeli (fourth generation, CEO) and Lukas Bischoff (CTO) with the support of all employees.
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.
