Abstract: 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.

Abstract: 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.
