The utility model discloses a round nose coating cutter with a stepped cooling channel, which comprises a fixed seat, a butt joint cavity, a milling cutter bar and a cooling unit, the butt joint cavity is arranged on the fixed seat in a penetrating manner, a mounting cavity is arranged in the fixed seat, the mounting cavity is positioned on one side of the butt joint cavity, and a locking component is arranged in the mounting cavity. Compared with the prior art, the cutter has the advantages that the effective contact area of cooling liquid and the cutter body is greatly increased through the design of the stepped variable-depth grooves, the critical heat flux density is improved through the micro-jet effect generated by the stepped structure, the effective cooling time is prolonged to be multiple times of that of a traditional cutter under the intermittent cutting working condition, and the cutting efficiency is improved. Compared with the prior art, the milling cutter bar has the advantages that the peeling rate of a cutter coating is greatly reduced, the service life of the milling cutter bar is greatly prolonged, meanwhile, the working efficiency is also improved, the milling cutter bar and the supporting bar with different diameters can be synchronously locked through the arrangement of the locking assembly, and the overall stability and the milling precision of the cutter during milling operation are improved.
