The numbers on saw blades serve as essential identifiers, typically denoting the blade's diameter, thickness, number of teeth, and arbor size, all measured in millimeters. For example, 350 signifies a 350mm diameter, while 2.5 refers to a 2.5mm kerf or cutting thickness. A 40mm arbor hole is represented by the number 40. The number of teeth is often marked separately since blades are stocked blank and teeth are cut per order. The letter Z universally indicates the number of teeth on the blade.
