Abstract: A staggered-teeth diamond saw blade includes a circular steel base and a side wall provided at an outer edge of the steel base. Multiple first diamond cutter heads and multiple second diamond cutter heads are alternately arranged at the side wall through laser brazing; multiple diamond teeth protection cutter heads are uniformly distributed on an external surface of the steel base through high frequency induction brazing; a pre-plating layer is preformed at a welding surface where the side wall is welded with the first diamond cutter heads and the second diamond cutter heads; a pre-plating layer is preformed at a welding surface where the external surface of the steel base is welded with the diamond teeth protection cutter heads. The diamond cutter heads of the present invention are staggered to thicken the thickness thereof while cutting concrete pavement and other materials at high speed.
