A cutting insert-shim assembly (700) that has a cutting insert (150) with interior coolant passages (300). A shim (704, 850) has a first side surface (780, 852) and a second side surface (782, 854) and contains a cavity (800, 882), which defines a first opening (802, 882) in the first side surface (780, 852) and a second opening (818, 882, 894, 896) in the second side surface (782, 854). When the shim (704, 850) is in a first condition, the first opening (802, 882) provides a first level of coolant communication to the cutting insert (150). When the shim (704, 850) is in a second condition, the second opening (818, 882, 894, 896) provides a second level of coolant communication to the cutting insert (150).
