Several methods have been employed to drill holes. Most of the time only mechanical methods have been thought up. These mechanical methods have a lot of disadvantages. Some of them being production of heat while drilling and also there was use of a lot of energy. Moreover, to drill both small and large holes is very difficult especially in hard and brittle materials using traditional drilling methods (Robert, H. & Allen, D, 1994). In some areas such as space, automobile, electronic sand computer (printed circuit boards), medical (Surgical implants), optics and miniature manufacturing provide the need for drilling holes in hard ...
