In the last years, the research on metal machining has been focused on the development oftools that can support an increment of the cutting parameters instead of the increment of tool life; thisstrategy is focused to obtain a relevant productivity increment without getting worse the final productquality. The new design of the tool corner radius has allowed preserving the same product quality due tothe “wiper effect” generated during the cut.The employ of such re-designed tools can allow substantial productivity improvements and, by employingthe same feedrate, it is possible to achieve excellent surface finish and eliminate the grinding operation.With the aim to verify the possibility to realize good finishing on hardened materials with the abovementioned new tool-manufacturing technology the Authors conducted a set of turning tests on a quenchedsteel.The quality of the manufactured products are compared with the one obtained by grinding. The finalproduct qualities are compared in terms of micro geometrical characteristics and tolerances of the obtainedworkpiece surfaces are investigated to completely determine its mechanical performances.
