Abstract: A cutting tool includes a toolholder and a cutting insert. The toolholder includes a toolholder pocket having a pocket wall including a first anti-rotation engagement surface and a second anti-rotation engagement surface. The cutting insert is mounted in the toolholder pocket. The cutting insert includes: an upper surface, the upper surface having a plurality circular sinusoidal cutting edges; a lower surface opposite the upper surface; and an exterior sidewall between the upper surface and the lower surface. The first anti-rotation engagement surface and the second anti-rotation engagement surface of the pocket wall of the toolholder engage the exterior sidewall of the cutting insert to resist rotation of cutting insert.

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.

Abstract: A cutting insert with internal coolant passageways is disclosed. The cutting insert includes at least one internal coolant inlet passageway having a first cross-sectional area, and at least one internal coolant exit passageway having a second cross-sectional area. The at least one internal coolant exit passageway is in fluid communication with the at least one internal coolant inlet passageway. The coolant enters the at least one internal coolant inlet passageway at a first surface of the cutting insert and exits the at least one coolant exit passageway at a second, different surface of the cutting insert. The second cross-sectional area of the at least one internal coolant exit passageway are less than the first cross-sectional area of the at least one internal coolant inlet passageway, thereby producing an increased streaming effect of the coolant to an insert-chip interface.
