摘要： An indexable cutting insert includes a rake face, a flank surface, a bottom surface, and a central aperture defined by an aperture side wall. The indexable cutting insert further has a mouth defined by a mouth surface. There is a primary coolant trough that has an aperture section in the side wall contained in the aperture side wall, a mouth section contained in the mouth surface, and a rake face section contained in the rake face. There is a radial angular coolant trough, which has an entrance end opening into a selected one of the primary coolant trough and the mouth. The radial angular coolant trough has an orientation wherein the central longitudinal axis thereof is generally perpendicular to a corresponding discrete cutting edge whereby during operation a coolant stream is directed toward the corresponding discrete cutting edge.
摘要翻译：可转位的切削刀片包括前刀面，后刀面，底面以及由孔侧壁限定的中心孔。可转位切削刀片还具有由口表面限定的口。主冷却剂槽具有容纳在孔侧壁的侧壁中的开口部，容纳在口部表面的口部以及容纳在前刀面上的前刀面部。存在径向角冷却剂槽，其具有入口端开口到主冷却剂槽和口中的选定的一个。径向角冷却剂槽具有取向，其中其中心纵向轴线大致垂直于相应的离散切割边缘，由此在操作期间冷却剂流被引向相应的分立切割边缘。

摘要： An indexable drill assembly includes a drill body, which has a head portion at the axial forward end thereof and wherein the head portion has an outboard pocket and an inboard pocket. The drill body contains an outboard pocket coolant channel adjacent the outboard pocket and an inboard pocket coolant channel adjacent the inboard pocket. The outboard pocket has a seating surface and the outboard pocket coolant channel opening at the seating surface. The drill body further contains an outboard retention screw aperture opening in the seating surface wherein the seating surface contains an outboard coolant ring surrounding the retention screw aperture wherein the outboard coolant is being in fluid communication with the outboard pocket coolant channel. The inboard pocket has a seating surface and the inboard pocket coolant channel opens at the seating surface. The drill body further contains an inboard retention screw aperture opening in the seating surface wherein the seating surface contains an inboard coolant ring surrounding the inboard retention screw aperture wherein the inboard coolant ring is in fluid communication with the inboard pocket coolant channel. The drill assembly further includes an indexable outboard cutting insert retained in the outboard pocket, and an indexable inboard cutting insert retained in the inboard pocket.
