Summary:
The utility model discloses a diamond blade with multiple cutter heads and multiple cutters, which comprises an equilateral triangle base body. The top end of the upper end surface of the base body is provided with a PCD cutter head at three ends, and a blind hole is arranged at the center, and the blind hole is provided. The side surface is machined with three equally spaced circumferentially arranged pin slots, the lower end surface of which is machined into a triangular pyramidal drilling section, the drilling section being machined with three curved main cutting edges, the curved cutting edges One end is at the top corner of the base body, and the other end is connected to the ladder-shaped blade. The ladder-shaped blade is also made of PCD material, and the top end of the three trapezoidal shaped blades is collected on the cone top of the triangular pyramid drill. The utility model has the advantages that the design of multiple cutter heads is equal to the disguised phase, which increases the service life of the cutter, and also increases the drilling function, so that the cutter can perform both surface processing and hole machining, thereby increasing the function of the utility model.
