Chamfering end mill

The invention discloses a chamfering end mill, comprising a handle part and a cutting part. The front cutter face and the rear cutter face of the cutting part intersect to form cutting edges, the cutting part is provided with at least two chip containing grooves obliquely extending from the small-diameter end to the large-diameter end, the shearing angle of each cutting edge is larger than 0 degree, and the shearing angle of at least one cutting edge is different from the shearing angles of the other cutting edges. The chamfering end mill disclosed by the invention has the advantages of high cutting efficiency, small cutting vibration, long service life and the like. 本发明公开了一种倒角立铣刀，包括柄部和切削部，所述切削部的前刀面与后刀面相交形成切削刃，所述切削部设有至少两个自小径端向大径端倾斜延伸的容屑槽，各所述切削刃的剪切角均大于0°，且至少一个所述切削刃的剪切角不同于其余切削刃的剪切角，本发明的倒角立铣刀具有切削效率高、切削振动小且使用寿命长等优点。
