Tesch

What Tesch does

Tesch (legal entity Diamant-Gesellschaft Tesch GmbH) is a German, family-owned manufacturer of diamond and cubic boron nitride (CBN) grinding tools, founded in Berlin in 1902 and now headquartered in Ludwigsburg, Baden-Württemberg. The company designs and produces grinding wheels, dressing tools, and related cutting tools across four bond systems — galvanic, vitrified, metal, and resin — with approximately 80% of output consisting of special/custom tools engineered to specific customer manufacturing processes. Proprietary technical capabilities include CFRP base body production, laser microstructuring of abrasive coatings, numerical simulation for base body design, and metal-bonded grinding wheels for machine-integrated erosive dressing.

The company serves a diverse set of industrial verticals including drive technology, automotive, glass/ceramics/plastics, mechanical and plant engineering, energy and communications technology, tool and mould construction, and forestry/agricultural equipment. It sells exclusively through direct field sales supported by globally acting application engineers, regional sales offices in China, Mexico, India, and the United States, and a network of worldwide operating agencies. Revenue is generated through one-time unit sales of custom and standard tools and through aftermarket services such as cleaning, recoating, re-profiling, sharpening, balancing, and repair — including third-party products. Pricing is quote-based (ex-factory), with 30-day payment terms for new tools and 10-day terms for repairs.

Tesch holds ISO 9001:2015, ISO 14001:2015, VDA 6.4, TISAX, and AEO certifications and operates production exclusively in Germany at two sites (Ludwigsburg and Döbern, the latter acquired in 1990 as Diaglas Döbern GmbH). The firm is in its third and fourth generation of family ownership, employs approximately 250 specialized staff, and maintains active research collaborations with multiple Fraunhofer institutes and German technical universities. Revenue figures are not publicly disclosed.
