AB The use of adhesive layers can improve the properties and reduce the defects producedin the interfaces. This provides adherence to the structure, adapting the joining surfaces andavoiding spaces between the layers. However, the presence of the adhesive can potentiate thedefects caused during drilling. In turn, a loss of adhesive in the interface can occur duringmachining affecting the final structure. This work has followed a conventional OSD strategy inCFRP and UNS A92024 aluminium sheet stacking with adhesive. A series of dry drilling tests havebeen developed with different cutting conditions and new noncoated WC-Co helical cutting tools.Analysis of Variance (ANOVA) statistical analyses and surface response models have been applied todetermine the mechanical behaviour in the holes. For this purpose, the dimensional deviation, surfacequality, and adhesive loss in the interface in relation to the number of holes have been considered.A combination of cutting parameters that minimizes the evaluated defects has been found. Diametricdeviations and surface qualities below 2% and 3.5  m have been measured in the materials that makeup the stack with cutting speeds higher than 140 m/min and feed rates between 200 and 250 mm/min.However, the greatest adhesive losses occur at high cutting speeds.
