How to Select a Suitable Type of Diamond Saw Blade

How to choose the right type of diamond saw blade? You can consider this from three aspects of the diamond blade:

1) The Grit of Diamonds: The commonly used diamond grit is between 60/80# to 30/35#. The harder the material to be processed is, the smaller diamond grit should be chosen, because smaller diamonds are more easily to cut into hard materials.

2) The Concentration of the Segment: The concentration is the percentage of the diamonds in the whole segment materials. Increasing the concentration can prolong the blades'life, because this will reduce the average pressure on each diamond when cutting. However, the increasing in concentration will inevitably increase the blade's cost. Therefore there is a most economical concentration for a certain cutting efficiency.

The diamond particles are normally distributed in the segment unevenly, and are usually made into a wave-shape. This will help to improve the service life and precision of diamond circular saw blades.

3) The Hardness of the Bond Materials in the Segment: In general, the higher hardness of bond materials, the stronger its abradability. As a result, when sawing the highly abrasive rocks, the user should choose a high hardness of the bond materials;
