Dry drilling is a process of interest in order to eliminate the lubrication fluids. Also the aeronautical industry has been expected to these advantages. This paper analyses the cutting forces obtained during the dry drilling of aluminium alloy plates, in particular UNS A92024-T3. Experiments were performed in CNC milling and several HSS Co drills were utilised with different diameters. Cutting forces were measured by means of a piezoelectric dynamometer Kistler. This analysis provides a statistical study, by means of multi-sample comparison, in particular, F-test in the analysis of variance. Results provide evidence that can provide information about hole drilling with a tool without wear, so forces are statistically similar.
