The article presents the research of a cutting tap that has a geometry that extends the cutting tool's life by reducing chipping when the tap reverses while still engaged in cutting a thread. It relates to the improvement of a spiral tap which discharges chips toward a shank via a helical flute. The article contains details about the tap geometries and the results obtained in this research, such as: tool life, chips comparison after cutting 1000 threads, surface comparison after processing 1000 threads and torsion moment analysis. Chip removal is an important factor in the process of threading blind holes which influences the life of the tool.
