Cemented carbide saw blades include multiple parameters such as the type of alloy blade, the material, diameter, number of teeth, thickness, tooth shape, angle, and aperture of the substrate. These parameters determine the processing ability and cutting performance of the saw blade. When selecting a saw blade, it is necessary to correctly select the saw blade based on the type and thickness of the sawing material, the sawing speed, the sawing direction, the feeding speed, and the sawing path width.
