The American manufacturer Diamond Machining Technology (DMT) is the founder of interrupted surface technology for diamond sharpening stones, and has been the market leader for diamond-coated sharpening equipment for years. The high-quality sharpening tools are manufactured at the company's headquarters in Massachusetts (USA).
Monocrystalline* diamond particles guarantee a long service life and excellent material removal
Uniform grit sizes and a dense diamond distribution for even grinding patterns
Round recesses prevent clogging due to grinding debris
Permanently flat and warp-free thanks to supporting plates made of steel or warp-free plastic with a nickel matrix
Diamond-coated sharpening devices remain permanently flat, and are especially suitable for tools with straight blades, as well as for producing flat surfaces (e.g. backs of plane and chisel blades, plane soles, scrapers). Also suitable for carbide coated cutters, tool steels, HSS and non-metal materials (glass, ceramic, etc.). We recommend moistening diamond-coated sharpening devices with water and grinding with little pressure. * Monocrystalline diamonds are significantly more wear resistant than the polycrystalline diamonds used to make lower quality diamond sharpening tools.
