削送りを大きくとれない問題点を有していた。However, in the former cutter, the number of blades is sufficient because the formed tip is wedged, but the wedge pressure deforms the groove of the cutter body. There was a problem that the precision of the cutting edge width was poor. Further, the latter cutter does not have a groove deformation problem by being screwed, but has a problem that the number of blades is practically small and a large cutting feed cannot be obtained.
