Mono Diamond Tool (Monocrystalline Diamond—MCD) The Mono Diamond Tool, also known as Monocrystalline Diamond (MCD), is a type of Single Crystal Diamond (SCD). It is a synthetic single-crystal diamond that ranks among the hardest materials, with mechanical properties comparable to natural diamond. MCD tools are ideal for final surface finishing processes that require glossy or mirror-like finishes. They are best suited for cutting non-ferrous materials, such as aluminum, brass, copper, platinum, silver, and various plastics. Mono Diamond Tools are widely used in the production of camera lenses, watch components, jewelry, medical instruments, and more.

A mono diamond tool is a cutting tool made from monocrystalline diamond (MCD), which consists of pure carbon synthesized under extremely high pressure and temperature. It features an ultra-sharp cutting edge, capable of achieving surface roughness levels of less than Rz 0.02 µ. During cutting, the tool generates very low cutting forces, which significantly reduces tool wear. As a result, mono diamond tools are ideal for final finishing operations, especially when a mirror-like surface finish is required. General Characteristics of Mono Diamond Cutting Tools Mono diamond tools, or diamond cutting tools, typically include V-shaped tools, T-shaped tools, and diamond-tipped cutters. These tools are primarily used for turning operations and can be custom-designed and manufactured in various forms—similar to PCD or carbide cutting tools. You can refer to the sample workpieces in the images above for visual examples.
