Rezumat: Glass fiber reinforced plastic (GFRP) composite materials are used in various fields because of their superior properties. The drilling process is the method mostly used in processing GFRP composites in chipping form. Since they are hard and abrasive, there appear problems in drilling these materials. The damages in entrance and exit of the holes are the most important of these problems. Therefore, in this study, drilling of GFRP composite material produced via lay-up method was executed at the cutting speeds of 60, 90 and 120 m/min; and at feed rate values of 100, 200 and 300 mm/min; and by o o o means of drill at 4, 7, 10 mm possessing point angles 90 , 118 and 140 without using cutting fluid. Depending on the damage in entrance and exit of the holes, deformation factor was calculated. It was observed that the damage occurring in the exit of the holes was greater than that of the entrance of the holes. It was found out that the minimum deformation occurred at low cutting speed and feed rates.
