We have tried to obtain an optimal abrasive system that can improve the quality of products or goods and the production efficiency by establishing the process system to manufacture 100micro drills and by experimenting it in various ways. This paper have decided the optimum nomenclatures of 100micro drill for the shape design by considering the important factors such as the cutting point angle, helix angle, web thickness, flute length and under cut etc through the FEM analysis and was evaluated the characteristics of it owing to getting the high quality's products by various experiments.
