Unirock

What Unirock does

Unirock SA is a privately held Swiss manufacturer founded in 1991 and headquartered in Biel/Bienne, Switzerland. The company develops and produces a comprehensive range of diamond and CBN (cubic boron nitride) grinding wheels spanning vitrified, electroplated, and metal bond systems, offered in more than twenty standardized profiles (e.g., 1A1R, 1A8, 14A1, 12A2, 6A2, CNC-compatible wheels, and specialized watch-decoration wheels). Its product portfolio is complemented by dressing wheels, diamond paste, corundum stones, rubber-bonded perloirs, resharpening machines, flanges, stakes, and expendable hones, together with a wheel dressing and resharpening service.

The company's commercial model is built on direct enterprise sales from its Swiss headquarters, supported by an international reseller network covering Germany (Friedrich Britsch GmbH & Co. KG), Belgium (Précicarb SA), Sweden (Ehn & Land AB), and the USA (Alouette Tool Co., Ltd.). Unirock also acts as the exclusive Swiss distributor for SCHOTT diamond tools and represents 3M abrasive bands, Krebs & Riedel grinding products, and the co-marketed Sarubin brand. Pricing is quote-based and not publicly disclosed. The customer base is concentrated in two verticals: the Swiss watchmaking industry (primary, where Unirock supplies grinding solutions for movement components, decoration, and finishing) and broader precision manufacturing (secondary, serving microtechnical production of glass, ceramics, hardened steel, and superalloys). Marketing and lead generation are driven primarily through trade show participation — notably SIAMS (Moutier) and EPHJ (Geneva) — rather than extensive digital channels.

Recent strategic activity has centered on product portfolio extension, specifically the April 2026 launch of a vitrified-bond grinder line, alongside joint go-to-market with Sarubin at SIAMS 2026 and continued EPHJ presence. The company shows no disclosed AI/ML capability, no external funding events, no M&A activity, and operates with a small identified leadership team (Président, Associé, Ingénieur commercial, and two sales administration/finance staff), characterizing it as a focused, founder-managed niche industrial supplier.
