Company history

In May 2002, Rolf Hemmann founded the company HEMAG in the old wire factory building in Biel. The company specializes in the manufacture of small precision parts made of hard metal, ceramics and steel. At the end of October, the transition to Hemmann Schleiftechnik takes place. The wife Esther Hemmann also actively helps to build up the company.

In October 2003, Rolf Hemmann and Christoph Ogi take over the company Theilkäs Frères from Brügg with all employees as part of a succession plan. The company Theilkäs Frères had been on the market for 30 years, specializing in the production of precision carbide tools for machining. The company is repositioned under the name HT Toolstar AG. Together with Hemmann Schleiftechnik GmbH, we can offer our customers a well-rounded product portfolio.


Esther Hemmann acquires Christoph Ogi’s shares in 2005.

A partir de janvier 2006, le fils Michael Hemmann fait également partie de notre équipe.

Certification according to ISO 9001:2008 Quality Management.

In June 2009, the company headquarters is moved to new, modern premises in Ipsach. Simultaneously, HT Toolstar AG is integrated into the company Hemmann Schleiftechnik GmbH.

Thanks to investments in high-precision machines and measuring equipment and our very high quality standards, Hemmann Schleiftechnik has been able to position itself on the national and international market.
