The concept "Development and Fabrication of Specific Tool to Produce Hexagonal Holes” is by the use of the drill and based on the of reuleaux pentagon. The aim of this project is investigate how a circular motion can be converted into a hexagonal motion by purely a mechanical linkage, an application of which is to construct a special tool that drills exact hexagon holes. The practical importance of this enhancement is that the driving end can be placed in a standard drill press; the other end, when restricted to stay inside the ambient hexagon, will yield a perfectly hexagon locus and this can be turned into a working hexagon hole drill. The fabrication of the developed design in this paper has been done on Steel (EN8) that is ideal for soft surfaces but if harder materials are used, hard surfaces application is also possible. Additionally, for this geometry to work from a rotating drive one must force the Reuleaux pentagon to rotate inside a hexagon, and that requires a hexagon template to constrain the Reuleaux pentagon as well as a special coupling to address the fact that the center of rotation also moves.
