Article Preview

Base on the conventional twist drill, the new type of solid carbide twist drill which the length-to-diameter radio (L/D) is about 12 was developed with improved parameters of drill point and flute geometry. Study of intensity and rigidity of drill was performed by using analysis software ANSYS Workbench for the theoretical support and technical guidance for the design of twist drill. Tests were carried out to compare the new drills with the competitive drills in terms of tool life, chip breaking, and chip disposal. The results obtained from tests indicated that the new type twist drills have similar cutting capability compare to the competitor’s drills.
