The utility model belongs to the field of tools made of super-hard materials, and particularly relates to a two-sided composite pcbn double-ended forming slotting tool. The two-sided composite pcbn double-ended forming slotting tool comprises a blade body, wherein the shape of a cutting end of the blade body is matched with a shape required to be cut; the blade body is provided with at least one cutting end; two cutting tool bits are machined at the cutting end of the blade body. Compared with the prior art, the two-sided composite pcbn double-ended forming slotting tool is made of a two-sided composite pcbn material, and solves the problem of high-speed cutting of a blade. According to the two-sided composite pcbn double-ended forming slotting tool, at least one cutting end is arranged on the blade, and two cutting tool bits are machined at the cutting end of the blade, so that through the utilization of the characteristics of pcbn, the service life of the cutting end is prolonged, the using frequency of the blade is increased, the production efficiency is improved, and the purchase investment of a company is reduced.
