Resumo: The main objective of this work is to investigate the influence of tip angle on fast steel helical drills in the deviation of cylindricity in the drilling process. Consequently, the study can also be expanded on the influence of the angle on the deviation of circularity, actual diameter and flank wear on the tool. To carry out the study, drills with a diameter of 10 mm were used, and as a base material, a segment of nodular cast iron used in the manufacture of bearings for hydraulic turbines. To perform the study, three drills with different tip angles (100 ° 120 ° and 140 °) were used, each tool made 20 through holes with a length of 20 mm in the base material, at the end of each 5-hole cycle The study on the progression of drill wear. At the end of the drilling process, the base part was routed to a coordinate measuring machine to check its deviations.
