About KGS DIAMOND
KGS DIAMOND is a fourth-generation Swiss family company headquartered in Lugano, with development, production and distribution of diamond grinding technologies. The company manufactures flexible diamond abrasives, sintered diamond cutting discs, diamond tools and high-precision metallised fabrics. Its proprietary manufacturing processes include sintering of metal and resin bonds, metallisation of fabrics, electroplating, spray coating and cold-bonded coated abrasives. In addition to tools for stone, glass, floor coverings and hard coatings, KGS offers a specialised four-disc programme for materialography (FLEXIS, TELUM, PROLAP, PROMET) that supports laboratories with sample-based microstructure analysis. The company serves industries such as natural and engineered stone, glass, ceramics, porcelain, metals, composites, automotive, aerospace, energy, mechanical engineering and electronics. With 21 locations in 15 countries, six production plants and more than 300 employees, KGS DIAMOND sells its products in over 100 markets worldwide.
