The diamond blade industry can track up to 600 heads. This is because diamond blades are designed to be used in a variety of applications, from cutting concrete and asphalt to cutting through metal and other materials. As such, the diamond blade industry has developed a variety of different blade designs to meet the needs of different applications. Each blade design has a different number of heads, ranging from one to six. The most common diamond blade designs have two to four heads, but some blades can have up to six heads. The number of heads a diamond blade can have depends on the application it is being used for and the size of the material being cut. For example, a diamond blade designed for cutting concrete may have two heads, while a blade designed for cutting metal may have four heads. The number of heads a diamond blade can have also depends on the manufacturer and the type of diamond blade being used.
