Cutter capable of cutting bidirectionally

The tool comprises a guide section, a cutting tooth section, a calibration tooth section and a rear guide part, and the guide section, the cutting tooth section, the calibration tooth section and the rear guide part are sequentially arranged; a guide structure with the same profile as a machined inner hole is adopted, and guiding can be achieved during forward and reverse cutting. In addition, the design of the bidirectional front angle push broach is beneficial for improving the cutting roughness, and the influence of rebound of a unidirectional cutting part on the size of a workpiece can be effectively reduced; therefore, the cutter well solves the problem that soft material parts such as aluminum alloy and the like rebound and deform after being cut, meanwhile, the working efficiency is improved, and the working cost is reduced. 本发明涉及一种可双向切削的刀具，包括导向段、切削齿段、校准齿段和后导部，所述导向段、切削齿段、校准齿段和后导部依次设置；采用和加工内孔相同廓形的导向结构，正反向切削时均可导向。而且，本发明双向前角推刀设计对提升切削粗糙度有益，能有效降低因单向切削零件反弹对工件尺寸的影响；因此，本发明刀具在很好地解决铝合金等软材料零件切削后反弹变形的难题的同时也提高了工作效率
