How to Choose Thickness of Tungsten Carbide Saw Blade? 82

How to choose thickness of tungsten carbide saw blade? Tungsten carbide saw blade may be made of tungsten-carbide cobalt – a metal matrix composite, where tungsten carbide particles are the aggregate, and metallic cobalt serves as the matrix. In theory, we hope to use a thinner blade, as it cost less. However, the choice of thickness of a saw blade should taking the stability of the saw blade during work and the material to be sawed into account. More details,…
