Ultrathin diamond saw blade

The utility model relates to the field of saw blades, in particular to an ultra-thin diamond saw blade which is used for avoiding the fact that a diamond blade is directly or indirectly installed on a saw blade base body through a welding technology, and further solves the technical problems that due to the welding technology, the diamond blade deforms, and the connection strength between the diamond blade and the base body is insufficient. The ultrathin diamond saw blade comprises a cutterhead and more than one diamond blade. The cutterhead comprises a pressure plate and a base plate, and the base plate and the pressure plate are provided with fastener mounting holes and are tightly connected through threaded fasteners. The diamond blade is clamped and kept between the base plate and the pressing plate so as to replace a welding connection mode to achieve connection of the diamond blade and the cutter head. By means of the arrangement, the diamond blade does not need to be directly or indirectly installed on
