A cutting assembly that is useful in an operation for chipforming removal of material from a workpiece. The cutting assembly includes a holder having a seat and containing a coolant delivery passage. A locking pin, which has a longitudinal locking pin bore, is affixed to the seat so the longitudinal locking pin bore is in communication with the coolant delivery passage. A cutting insert has a rake surface, a corner cutting edge region, a central cutting insert aperture, and a radial coolant trough with an orientation toward the corner cutting edge region. At least a portion of the locking pin is within the central cutting insert aperture. A clamp assembly attaches to the holder and engages the cutting insert. The clamp assembly has a diverter plate, which has a bottom surface defining a diverter bowl and a diverter channel. The longitudinal locking pin bore opening to the diverter plate whereby coolant flows into the diverter bowl and through the diverter channel into the radial coolant trough toward the corner cutting edge region.
