Girl, would you like to ask if the stone saw blade teeth are broken and can the size be changed? Stone saw blades cannot be resized if their teeth are broken. Stone saw blades are tooth-shaped. When making precision workpieces, you cannot use saw blades with missing teeth. The surface of the saw blade will be uneven when cutting things. After the teeth are broken and the size is changed, the size of the precision workpiece will change. Changes will be very different from the original needs, so the size of the stone saw blade cannot be changed if the teeth are broken.
