Based in Marlborough, Massachusetts, since 1976, DMT® Diamond Machining Technology has been the leader in, and innovator of, a full range of dependable diamond sharpening products and has gained an excellent reputation for solving a multitude of sharpening, honing or deburring needs.
The US-based company Diamond Machining Technology, (DMT) is the leading manufacturer of quality diamond sharpening stones. DMT tools are precision manufactured, highly wear resistant and extremely effective. The monocrystalline diamonds*, permanently embedded in a nickel matrix, guarantee remarkable sharpening speed even when working the hardest tool steels. The diamond-coated blocks remain permanently plane, and are especially suitable for tools with straight blades as well as for producing plane surfaces (e.g. backs of plane and chisel blades, plane soles, scrapers). Also suitable for carbide coated cutters, HSS, as well as non-metal materials (glass, ceramic etc.). We recommend moistening the DMT stones with water and grinding with little pressure.
