What K&Y Diamond does
K&Y Diamond is a Canadian manufacturer of ultra-precision diamond cutting tools, headquartered in Dollard-des-Ormeaux, Quebec. Founded in 1976 (with firmographics indicating 1976 and a separate source noting 1970), the company employs 11-50 people and combines more than 50 years of diamond cutting expertise originating from German and Swiss engineering traditions. K&Y produces single crystal natural diamond, HPHT synthetic diamond, CVD synthetic diamond, PCD (polycrystalline diamond), and PCBN (polycrystalline cubic boron nitride) tools for industries requiring nanometer-level tolerances, including ophthalmic lens manufacturing, electro-optics, spectacle lens production, jewelry and watchmaking, and precision machining of non-ferrous metals and hardened steels. The company claims worldwide leadership in waviness control, achieving surface waviness as low as 0.02 microns, supported by inspection at 800x (DIC microscope) and up to 50,000x (SEM) magnification, all produced in an ISO 9001:2015-certified facility completed in 2018.
The company operates a sales-led go-to-market model with custom quote-based pricing and drawings provided for approval before manufacturing. Products are organized across five solution areas: Contact Lens/IOL Tools, Electro-Optics Tools, Spectacle Lens Tools, Jewelry/Watch Making Tools, and PCD & CBN Tools, with a portfolio of downloadable brochures and care guides. Beyond one-time tool sales, K&Y generates a recurring service revenue stream through a Relapping/Repair Service capable of restoring precision tools up to 30 times, extending tool life and creating ongoing customer relationships. Distribution combines direct factory shipping from Montreal (with a US receiving facility in Champlain, NY operated through NFI Industries) and a network of certified global distributors. In Q1 2026, K&Y was acquired by Swedish industrial group Sandvik AB as part of Sandvik's strategic acquisitions, transitioning the company from founder-led private ownership to a wholly-owned subsidiary within a global industrial conglomerate.
