KGS Diamond Group

What KGS Diamond Group does

KGS Diamond Group is a Swiss family-owned industrial manufacturer founded in 1906 (manufacturing operations began 1952) that designs, produces, and sells flexible diamond abrasives, superabrasive tools, and metallised technical fabrics. Its product portfolio is organized around proprietary platforms including Flexis, Telum, Swiflex, Hybrid, Speedline, MetaFab, MEFFAB, and the QRS quick-release system, plus the FERRONATO consumer accessories brand. The technology is rooted in materials science — engineered diamond dot patterns, specialized backings (BPR, FSB), metal-bond and resin-bond formulations, and conductive metal coatings (nickel, copper) on woven/knitted/non-woven substrates for EMI/RFI shielding of 40–90 dB.

KGS serves nine industrial verticals — stone and construction, floor treatment, glass processing, hard coatings, materialography, metallised fabrics, porcelain, composites, and ceramics — supplying OEMs, distributors, engineers, and professional end-users. The business model is B2B and quote-based, with revenue generated through a hybrid direct-sales and distributor model. Distribution is supported by 6 production sites, 20 sales offices across 4 continents, and a presence in 100+ markets; the company employs 400+ people globally. Headquartered in Châtel-St-Denis, Switzerland, with primary manufacturing in Elburg, Netherlands, KGS uses trade shows (Marmomac, Big 5 Construct Saudi) and partnership recruitment as primary go-to-market channels, and in 2025 joined the SEAM sustainability program under FEPA while completing a corporate carbon footprint assessment.
