Please make adjustments according to the machining conditions. (Note 2) Vibration is liable to occur in certain cases. Please reduce the depth of cut and / or reduce cutting conditions in the following cases. When using the long shank type and extra long shank type. When using long tool overhang with the standard or arbor type. When the application has poor clamping rigidity or when using a low rigidity machine. (Note 3) In case of coarse and fine pitch cutters, the coarse pitch type is recommended to prevent vibration. (Note 4) For heavy interrupted and unstable cutting, the H breaker is first recommendation.
