Design and Analysis of Stainless Steel Twist Drills Li Zhengwei

Abstract:To raise the working efficiency of the stainless steel material drilling and the working life of the twist drills， this passage is to study the targeted geometric parameters design， including spiral flute， drill point and pointed angle.The twist drills can effectively overcome the problems of poor cutting performance and it is hard to process. The stainless steel twist drills use high performance high speed steel. By using the comparison and verification of the cutting experiment， this passage analyzes the reliability of the new design stainless steel twist drills.
