Abstract: Drilling of polymer composites by means of traditional tools does cause a significant amount of damage to the surface. The forces generated during drilling are the major factors that exert an influence on hole quality. This makes the design and development of the drill geometries an area of paramount importance. Over the years, several tools have been developed and commercialized to minimize the damage induced by drilling. In this technical paper, we presented and discussed about an innovative tool point geometry that was designed, developed, and implemented for the purpose of investigating the drilling performance of composite laminates. The performance of the developed drill bit is compared with extensively used twist drill bit in reference to the drilling induced forces and damage. The input parameters considered are tool point geometry, speed, and feed. Results of this investigation reveal that both forces and damage are significantly reduced when holes are produced using the developed drill bit. © 2017 Taylor & Francis.
