Superabrasives and diamond wheels includes a wide variety of cutters and grinding tools that use diamond or cubic boron nitride (CBN) abrasive grit as the cutting medium.  These devices, including diamond wheels, abrasive saw blades, wheel dressers, grinding wheels and single point tools are used in applications where extreme strength and abrasiveness is required as diamond and CBN abrasive grains are among the hardest known materials. CBN superabrasives are used in steel grinding applications where even diamond abrasives fail to perform.  For the most part, products in the superabrasives and diamond wheels category are rotary devices which perform their grinding or cutting actions as they spin against a given material.

Superabrasives and diamond wheels perform their function using either diamond or CBN grit.  Synthetic diamond is produced synthetically in a high temperature, high-pressure process anvil press. Diamond is superabrasive grain with the highest known hardness and a cubic crystal structure. It is used for grinding nonferrous metals, ceramics, glass, stone, and building materials. Diamond is not useful in grinding steel or ferrous alloys because carbon or diamond readily dissolves or reacts with iron. Cubic boron nitride (CBN) is superabrasive grain with hardness second to diamond and a cubic crystal structure.  CBN provide super grinding performance on carbon and alloy steel.  Diamond is not useful in grinding steel or ferrous alloys because carbon or diamond readily dissolves or reacts with iron.  CBN is also produced synthetically in a high temperature, high-pressure process anvil press; a process similar to synthetic diamond production.

In addition to their diamond or CBN constituency, some superabrasives and diamond wheels are designed with additional features to provide additional strength and performance life.  Some superabrasives and diamond wheels have an abrasive grain with a metal layer or coating.  These metal clad superabrasives are able to dissipate heat and enhance bonding.  Ceramic grinding wheels are also available that can handle the high degree of stress that superabrasives and diamond wheels consistently encounter.
