A metalcutting insert (150) that is useful in chipforming and material removal from a workpiece. The metalcutting insert (150) includes a metalcutting insert body (152, 154), which includes a cutting edge (160) having at least one discrete cutting location (161A-161F). The metalcutting insert body (152, 154) further contains a distinct interior coolant passage (300) communicating with the discrete cutting location (161A-161F). The distinct interior coolant passage (300) has a coolant passage inlet (304) defining a coolant passage inlet (304) cross-sectional area, a coolant passage discharge (302) defining a coolant passage discharge (302) cross-sectional area, and an axial coolant passage length. The distinct interior coolant passage (300) defines a coolant flow cross-sectional area along the axial coolant passage length thereof.; The coolant passage inlet (304) cross-sectional area is substantially the same as the coolant passage discharge (302) cross-sectional area. The geometry of the coolant flow area cha
