description The utility model relates to a knife tool for the chamfering of an oblique gear, particularly a knife tool for the bilateral chamfering of an oblique gear. The utility model has the technical proposal that the utility model is composed of two knife blades (3, 5), and a knife body (4), wherein, the knife blades (3, 5) are fixed to the knife body (4). The teeth surface at one side of the knife blade is a straight teeth surface which has the same transverse module and the transverse pressure angle with the oblique gear, the other side of the knife blade is an oblique teeth surface, and a cyclotomic helical angle is appreciably bigger than the helical angle of a work piece. Adopting the utility model, the straight teeth surface can make chamfering for the sharp edge of the oblique gear, and the oblique teeth surface can make chamfering for the root edge of the oblique gear. The utility model has the characteristics of reasonable structure, easy use, high production efficiency, long service life of the knife tool, etc. The utility model can simultaneously make chamfering for the root edge and the sharp edge of the oblique gear, and thus the utility model solves the problems of impact and noise generated by that the root edge of the oblique gear is knocked.
