The exposure or protrusion height of diamond on the cutting surface of the sawing tool will affect the cutting depth of each particle, that is, the material removal rate of the cutting tool. The use of diamonds with larger particle size will have a faster material cutting rate. Generally coarse particles are used for cutting soft materials, while smaller particle sizes are used for cutting hard materials.

The size of diamond determines the number of particles per carat. As the particle size number increases, the number of particles per carat increases. Because the number of diamonds on the cutting area of the tool has an impact on the life and power consumption of the tool, choosing the right mesh is the key to ensuring the performance of the tool. Generally speaking, the use of fine-grained diamonds for low-concentration floor grinding diamond tools can increase the number of diamond particles on the surface of the cutting tool, which is conducive to improving the service life and also increasing power consumption.

In addition to the diamond size, the concentration of diamond also determines the number of grains on the surface of the cutting tool. The higher the diamond concentration, the greater the number of crystal grains on the surface of the cutting tool, which is conducive to improving the life.
