Abstract
Fluid passageways are defined by the top plate, tool holder body and the cutting insert to permit the optimum cooling of the interface between the insert and the work piece reducing degradation of the cutting edge of the insert. A number of top plate designs with channel configurations are disclosed to provide the desired coolant flow distribution and accommodate the desired flow rate.
