Abstract—This paper highlights on the drilling characteristics of various drill bits while drilling a microwave
(MW) transparent material in a customized MW applicator. An attempt was made to investigate
the feasibility of drill bit of different microwave reflective materials in a 2.45 GHz microwave
applicator. The behavior of electrically conductive material was found to be more suitable as a
drill bit for microwave drilling. Seven different types of drill bit were used while drilling hole in
perspex work material. The test were performed in controlled atmosphere of domestic microwave
applicator for less than 300 s. Observations could help while selecting a suitable drill bit with
suitable size, shape and material for microwave drilling applications.
