Diamond Cutting Discs for Wet Cutting – Precision and Durability for Tilers

Diamond cutting discs for wet cutting are an essential tool for professional tilers who require precise, clean and material-efficient cuts on hard or sensitive construction materials. At the Karl Dahm online shop, you’ll find a wide range of high-quality wet cutting discs tailored specifically to the needs of the tiling trade. Whether you’re working with porcelain stoneware, natural stone, hard stone or granite – our discs deliver accurate results with maximum efficiency.


Why Wet Cutting? – Key Benefits at a Glance

During wet cutting, the disc is continuously cooled with water while cutting. This reduces friction, lowers the temperature and prevents chipping or cracking of the material. Additionally, dust development is minimised – an important advantage when working indoors.

Your benefits at a glance:

  • Increased service life thanks to continuous cooling

  • Chip-free edges – ideal for delicate tiles

  • Less dust, improved safety on site

  • Faster cutting due to reduced resistance
