Bevel cutting keyway broaching tool

The invention discloses a bevel cutting keyway broaching tool. The bevel cutting keyway broaching tool comprises tool teeth of the keyway broaching tool and a tool body, wherein the tool teeth of thekeyway broaching tool is prepared from hard alloy, the tool body is prepared from alloy structure steel, and the tool teeth are embedded in the tool body. The hard alloy tool material is adopted, thebroaching speed can be high, the tooth lift is large, the broach length is short, and therefore the broaching efficiency is high. Besides, the wear resistance and the heat resistance of the hard alloytool material are better than those of high-speed steel, so that the service life of the tool is long. 本发明的一种斜角切削键槽拉刀，包括硬质合金制备成键槽拉刀的刀齿和合金结构钢制备成刀体，所述刀齿镶嵌在刀体，采用了硬质合金刀具材料，可以用较高的拉削速度，而且齿升量较大，拉刀长度较短，所以拉削效率高，而且硬质合金刀具材料其耐磨性和耐热性比高速钢好，使得刀具寿命长。
