| Abstract: | The causes of hole broadening in the drilling with dissymmetric side edges are analyzed. The experi- ment of measuring the hole's diameter in the drilling with the dissymmetric side edges has been run. In addition, a new type of side edges of the twist drill is put forward in this paper. As a result of using this type of dissymmetric side edges in the drilling, the radial force is reduced and the accuracy of the hole drilling is improved. |
