Note: The given cutting values are guide values, which were determined under ideal conditions. The values have to be adapted in individual cases. With hole depths of 5xD adjust the cutting data accordingly to the application. f-group = feed rate recommendations on page C140. For examples of material for cutting tool groups view page D22.
