Cutter for processing graphite material

The utility model relates to the technical field of die processing, in particular to a cutter for graphite material processing, which comprises a cutter body, a bottom blade positioned at one end of the cutter body and a plurality of blades adjacent to the bottom blade and spirally arranged on the annular side of the cutter body, a cutter groove is formed between every two adjacent blades, the diameter of the bottom blade is 0.275-0.3 mm, and the diameter of the bottom blade is 0.275-0.3 mm. A receding groove is formed in the center of the bottom blade, the front angle of the blade is 6 degrees, the rear angle of the blade is 0 degree, the blade comprises an arc portion connected with the bottom blade and an inclined receding portion connected with the arc portion, and the cutting edge of the bottom blade is 0.02-0.05 mm lower than the center of the bottom blade. The cutter can increase the linear speed, improve the cutting capacity, reduce the surface roughness of the die, guarantee the machining consistency
