Diamond saw blades are difficult to distinguish in appearance. Saw blades belong to the category of tools, similar in appearance, it is difficult for non-professionals to see the difference.

1. First, check whether the cutting head on the diamond saw blade is in the same straight line

If the cutting head is not in the same straight line, it indicates that the size of the cutting head is not regular and may be wide or narrow, which will lead to unstable cutting when cutting stone and affect the quality of the saw blade.

2. Observe whether the weld is close to the matrix

Before the welding seam and the matrix, there will be a welding seam after the brazing. If the arc-shaped surface at the bottom of the tool head is completely fused with the matrix, there will be no gap. Such a gap indicates that the tool head on the diamond saw blade is not completely fused with the matrix, mainly because the arc-shaped surface at the bottom of the tool head is not evenly polished.

3. Measure the weight of the saw blade

The heavier the diamond saw blade, the thicker the better, because the heavier the saw blade, the greater the inertia force when cutting, cutting more stable. Generally speaking, 350mm diamond saw blades should be about 2kg, 400mm diamond saw blades about 3kg.

4. Check the hardness of the matrix

The higher the hardness of the matrix, the less likely it is to deform. Therefore, whether the matrix hardness reaches the standard during welding or cutting directly affects the quality of the saw blade. No deformation at high temperature welding or under the condition of force majeure is a good matrix, and it is even a good saw blade after being processed.

The above is the way to judge the quality of diamond saw blades. When you buy diamond saw blades, you can choose according to the above method.
