Kardiam

What Kardiam does

Kardiam Diamantwerkzeuge GmbH is a German manufacturer of professional diamond tools, founded in 1979 and headquartered in Wangen-Schauwies, Germany. The company specializes in tools used for canal and pipe rehabilitation, producing diamond drill crowns, diamond saw blades, and a broader portfolio of accessories designed to fit all major rehabilitation robot brands operating in the sewer and pipe renovation industry, including systems from KATE, PMO, Hächler, ProKasro, Schwalm, IMS, IBG, I.S.T., and IBAK. Beyond its catalog products, Kardiam offers custom manufacturing (Sonderanfertigungen), producing bespoke tools based on specific customer requirements, and positions fast delivery enabled by high inventory availability as a core competitive strength for its worldwide customer base.

The underlying technology is conventional industrial diamond tooling — synthetic diamond segments bonded to metal cores for cutting, drilling, and grinding applications in concrete, masonry, and pipe materials. The differentiation lies not in proprietary tool geometries disclosed, but in deep domain specialization: Kardiam operates exclusively in the niche of sewer/canal rehabilitation tooling rather than as a general diamond tool maker, and maintains broad cross-brand robot compatibility, making it a robot-agnostic supplier for operators running mixed fleets. The company runs a website with a product finder, downloadable catalogs, and a news/calendar section indicating active participation in industry trade shows.

The business model is B2B direct sales of physical hardware (diamond tools) under a quote-based pricing system, with no publicly disclosed pricing. Customers — professional canal and pipe rehabilitation companies worldwide — can order via phone, email, WhatsApp, website contact form, or the e-commerce storefront at kardiam.eu with account login functionality. With only 1–10 employees, no disclosed subsidiaries, no funding history, and no publicly identified management team, Kardiam appears to be a privately held, owner-operated industrial niche manufacturer serving a global but specialized customer base.
