INDEXABLE TANGENTIAL CUTTING INSERTS AND CUTTING TOOL HOLDERS

Abstract:

Cutting tool systems including a tool holder and tangential cutting inserts are disclosed. The tangential cutting inserts have indexable cutting edges that may be sinusoidal-shaped and helical-shaped. The tangential cutting inserts have integrated fan and base portions. The tool holders comprise a plurality of insert pockets structured and arranged to receive the indexable tangential cutting inserts. The cutting tool systems provide cutting tools with effectively longer sinusoidal and helical cutting edges at their cutting rake faces and a strong support when seating in insert-receiving pockets on the tool holder.
