This research is a study designed to compare the production efficiency of a complete left-handed operator when handling a modified pedestal drill, with the force controls on the left side of the machine versus a right-handed operator operating an unmodified pedestal drill. Through a descriptive study of ten men from five small metalworking companies located in northern Quito, Ecuador, with an average age of 19.5 ± 1.4 years and an average drilling experience of 5.7 ± 2.7 months, productivity was evaluated with SPC (Statistical Process Control) and drilling quality with MSA (Analysis of Measurement Systems). As a first step, the operators were evaluated and categorized through the Edinburgh protocol (quantitative laterality analysis), obtaining a population of 100% "consistently left-handed". Subsequently, a comparative analysis was made between the theoretical and experimental forces that the operator needs to perform a complete drilling, Force that serves as an input for SPC and MSA. Finally, a study of the times of a left-handed person in the drilling process in the modified and unmodified machines was carried out. Concluding that the efficiency of the left-handed operator decreases according to his degree of laterality when operating a drill without modifications.
