Bond is the metal (or resin) which holds the diamond segment together. The metal bond is an alloy containing different metals for different hardness' of the bond. The segment is designed to wear away always leaving a new layer of diamond. The bond is chosen based on the hardness of your concrete. For example, a soft bond would be used on hard ...

Another factor that affects the choice of wheel bond is the wheel speed in operation. Usually vitrified wheels are used at speeds less than 6,500 surface feet per minute. At higher speeds, the vitrified bond may break. Organic bond wheels are generally the choice between 6,500 and 9,500 surface feet per minute.

Abrasive wet cutting is the most appropriate materialographic cutting method, as it introduces the least amount of damage in relation to the time used for the process. Abrasive wet cutting employs a cut-off wheel, consisting of an abrasive and a binder. Cooling liquid flushes the wheel to avoid damaging the sample with frictional heat.

Made of abrasive grain and a binder, or "bond," it is a self-sharpening cutting tool. As the grains on the periphery become dull, they are shed from the surface of the grinding wheel, and fresh, sharp cutting edges are exposed. The ability to resharpen is controlled by the nature of the bond used and the ratio of abrasive to bond, measured ...

Metal Bond Tools are made with a different bond hardness for different types of concrete. Soft concrete is very abrasive and will wear out your diamonds faster. You should use a harder bond (Lavina Yellow metals), so it can last longer. Hard concrete requires a soft bond tool (Lavina Red, Gold or White metals) to avoid diamond glazing, where tools just slide on the concrete surface.
