Abstract
A metalcutting insert that is useful in chipforming and material removal from a workpiece. The metalcutting insert includes a metalcutting insert body, which includes a cutting edge having at least one discrete cutting location. The metalcutting insert body further contains a distinct interior coolant passage communicating with the discrete cutting location. The distinct interior coolant passage has a coolant passage inlet defining a coolant passage inlet cross-sectional area, a coolant passage discharge defining a coolant passage discharge cross-sectional area, and an axial coolant passage length. The distinct interior coolant passage defines a coolant flow cross-sectional area along the axial coolant passage length thereof. The metalcutting insert further includes a plurality of surface features for enhancing coolant flow to the cutting edge.
