There are 3 main criteria when evaluating the performance of a diamond saw blade: cutting efficiency, service life and processing quality.

Diamond grit indicates the size of the diamond. The diamond’s protrusion height on the cutting surface of the diamond saw blade influences how deep the diamond can cut, while deeper cutting means higher cutting efficiency. If the diamond is big, its exposed portion can be higher, so its cutting efficiency can also be higher. Therefore coarser diamond grit leads to higher cutting efficiency of the diamond saw blade.
The meaning of a diamond tool’s diamond concentration is the weight of the diamonds in a unit volume of the diamond tool’s working layer, and it is defined that when each cubic centimeter contains 0.88g diamonds, the concentration is 100%. This definition also applies to CBN abrasives.
Diamond grinding has many benefits. It is fast, low-noise and low-cost. It is very popular in the construction and home improvement industry. Diamond cup wheels are the diamond grinding tool which is often used to grind concrete, stone and masonry materials.
When you are going to buy diamond saw blades, you should first identify what kind of blades you need. If the diamond blades’ quality is much higher than your needs, you will waste your money; if their quality is lower than your needs, you (or your customers) will not be able to complete your (or their) jobs; if there are no problems with the diamond blades’ quality, but the blades just do not match the objects to be cut, you also can’t do your jobs well.
In my previous article about how to choose diamonds’ grit, I said some main points you should consider. There are still many other points which are also important.
When choosing the diamonds’ grit of a diamond tool, we should consider the workpieces’ roughness requirement, the tool’s cutting/grinding efficiency and the best grit range of the tool’s bond.
The bond of a diamond tool is mainly determined by the tool’s use. There are mainly three types of bond: resin, ceramic and metal.
Diamond concentration of a diamond tool means the weight of the diamonds in each cubic centimeter of the diamond tool’s working layer. The international standard has prescribed that if each cubic centimeter contains 0.88g super-abrasives, its concentration is 100%. The each increase or decrease of 0.22g will cause the concentration to change by 25% correspondently.
Grinding Tools are normally brittle, and in most cases are used in the status of high-speed rotation, so they should be kept carefully from being damaged. Below are some tips:
