The invention provides an efficient and novel PCD cutter set which comprises a connecting rod, wherein one end of the connecting rod serves as a connecting end, the other end of the connecting rod serves as a
cutting end, a facing cutter is arranged at the
cutting end, a plurality of
chip grooves are evenly formed in the periphery of the facing cutter, a first blade, a second blade and a third blade are arranged on the facing cutter, the structure is simple, the design is reasonable, finish milling, semi-finish milling and rough milling are integrally combined on one disc
milling cutter, cutter replacement frequency is lowered, the
processing time is saved, a great amount of man power and
material resources is saved, the
cutting speed is relatively high, the workpiece removing rate is high, the integral production efficiency is improved, the milling effect is relatively good, the precision is high, errors are small, the cost is relatively low, due to the arrangement of the
chip grooves, a
chip accumulating layer, which is caused by chip residual during cutting and impacts the work efficiency and the service life of the cutter set, is effectively prevented, and requirements of manufacturers are be met.
