Summary:The utility model discloses a composite cutting tool. The composite cutting tool comprises a tool holder and a working portion which is used for performing boring, chamfering and end surface milling; the working portion is of a stepped structure; the working portion comprises a boring section and a milling section from bottom to top in turn; the milling section is provided with an end surface milling cutter and a chamfering cutter; the boring section is provided with a boring cutter. During usage, the boring is performed on a part through the boring cutter of the boring section, the chamfering cutter and the end surface milling cutter which are arranged on the milling section work simultaneously when the boring starts to be performed on the milling section, the end surface located at the position of a hole is milled, and the edge of the hole is chamfered. According to the composite cutting tool, the structure is simple, the design is reasonable, the separate process of the existing surface milling, boring and chamfering is changed to the simultaneous boring, chamfering and surface milling at a time through the cutting tool which is arranged in an integrated mode, the three processes can be achieved through one-time machining, and accordingly the production efficiency is greatly improved.
