The diamond segments used on large diamond circular saw blades or diamond gang saws for cutting stones can be layered and have some non-working layers separating the working layers. The working layers contain the common materials of diamond segments, including diamonds and metal bonding materials, while the non-working layers are usually made of metal powders. This design can increase the sharpness of the diamond segment, and lower its production cost.

Diamond segments are the function parts of a metal-bonded diamond tool. The metal-bonded diamond tool can be a metal-bonded diamond blade, a diamond grinding cup wheel, a diamond core drill bit, a diamond gang saw blade, etc. The diamonds of a metal-bonded diamond tool are all in the tool's diamond segments to play their role of cutting or grinding.
