The aggressiveness of an abrasive tool describes the cutting performance the tool delivers while removing stock / cutting the material it is processing. Indicators of an abrasive tool's aggressiveness are stock removal per unit of time / the time required per cut.
Aggressiveness can be influenced during the production of the abrasive tool by enhancing the quality and the properties of the abrasive grain itself and by the integration of the grain into the backing material. The aggressiveness of diamond cutting blades can, furthermore, be influenced by the segmentation of the cutting edge.
More aggressive abrasive tools allow for shorter processing times. On the flip side, higher aggressiveness usually also translates to grinding surfaces of poorer quality and, at times, a shortened service life of the tools.
To enable the user to select the abrasive tool that is suited best for his particular application, Klingspor groups their rotating tools used for grinding and cutting by aggressiveness and service life in addition to categorising them by the three Klingspor performance classes (Extra, Supra, Special).
If the user attaches great importance to a high level of aggressiveness (in other words, short cutting and grinding times) and, thus, to rapid work process and short processing times, he can select tools that are categorised accordingly.
