Schott Diamond Tools

What Schott Diamond Tools does

Schott Diamantwerkzeuge GmbH is a German manufacturer of precision diamond and CBN (cubic boron nitride) cutting, grinding, drilling, and milling tools, headquartered in Stadtoldendorf and founded in 1975 by Klaus Schott. The company serves glass and ceramics, dental and medical technology, optics, automotive, aerospace, semiconductor, and university R&D customers with custom-configured tools produced via galvanic, sintered, and resin-bonded manufacturing processes. Its patented HM-GVD process enables galvanic diamond tools from 1mm diameter with direct bonding to tungsten carbide shafts without thermal stress, achieving h5 shaft tolerances and ultrasonic-compatibility, a differentiator versus traditional brazed tools.

The business operates a direct B2B field-sales model with on-site application engineering, quote-based pricing, and bespoke Sonderwerkzeuge (custom tools) developed from specification through prototyping to series production, with 100% quality control per tool. Revenue streams include one-time diamond and CBN tool sales, custom tool development, a ToolShop automated inventory management platform (with hardware, software, and ongoing support), Komplettlösungen turnkey machine-plus-workflow projects, and tool repair and re-sharpening services. Distribution is direct, no third-party resellers or e-commerce storefront, supported by a team organized by binding type and sales leadership.

The company added a second location via the August 2025 acquisition of DTS Handelsgesellschaft mbH in Mönchengladbach and launched a smaller-diameter HM-GVD product line in January 2026. It remains privately held under Lein-family management since 2005, with no external institutional funding, and holds ISO 9001:2015 certification across 20 consecutive years.
