Karl Dahm & Partner

What Karl Dahm & Partner does

Karl Dahm & Partner GmbH is a family-owned German specialty manufacturer and merchant of professional tiling tools and construction equipment, founded in 1956 by Karl Dahm in Seebruck am Chiemsee and now in its third generation of family leadership. The company develops, produces, and distributes a comprehensive portfolio spanning tile cutters (High-Line series with patented guide rail and Superknacker-based breaking device), tile leveling systems (Levelmac pull-based and Keile wedge-based), diamond drill bits (MATRIXTEC matrix-segmented dry drill bits, Gold paraffin-cooled dry drill bits, Bohrmeister wet core bits), diamond grinding cups and cutting discs, stone cutting machines, spirit levels, laser measuring devices, and finishing/consumable accessories, alongside curated third-party brands such as Bosch, FLEX, SOLA, STABILA, Sigma, and Montolit.

Technically, the portfolio rests on proprietary mechanical innovations developed over 65 years, including the original Fliesenhexe tool, the Superknacker breaking mechanism, the Levelmac pull-based leveling system for large-format tiles up to 3m, and MATRIXTEC diamond matrix segmentation with paraffin cooling — all addressing pain points in precise cutting, lippage prevention, and dry-drill heat management on construction sites. Select products are designated Made in Germany, and the product range spans hand tools, accessories for standard power tools such as Bosch GWS 12V-76 angle grinders, and standalone electric machines.

The business model is direct-to-consumer e-commerce through karldahm.com, supplemented by telephone, WhatsApp, fax, email, and physical pickup at the Seebruck headquarters, with worldwide shipping and no minimum order value. Revenue comes from one-time hardware sales across individual pros, commercial dealers (via individualized bulk pricing), apprentices, and DIY homeowners; pricing spans roughly €5 to €3,000 per item, with VAT-excluded options for business customers and a separate discounted SALE category. Marketing relies on social video content (YouTube, Instagram, Facebook), a free annual catalog, WhatsApp-based direct support, and trade seminars through the Akademie des Handwerks, targeting primarily German-speaking professional tilers while shipping globally.
