Claim:
1. A tool holder for carrying a cutting insert wherein the cutting insert is useful for the removal of material during a material removal operation, the tool holder comprising: a tool holder body comprising: a pocket adapted to carry the cutting insert, a coolant inlet in communication with a pressurized source of coolant, a coolant chamber having a central region, an upstream coolant passage having a central longitudinal upstream coolant passage axis; a plurality of downstream coolant passages wherein each downstream coolant passage has a central longitudinal downstream coolant passage axis, each of the downstream coolant passages terminating in an opening; and the upstream coolant passage opening into the coolant chamber, and the upstream coolant passage having an orientation relative to the coolant chamber so that the central longitudinal upstream coolant passage axis is offset from the central region of the coolant chamber whereby coolant flows into the coolant chamber in a tangential fashion; wherein each of the downstream coolant passages receives coolant from the coolant chamber, and each of the downstream coolant passages having an orientation relative to the coolant chamber so that the central longitudinal downstream coolant passage axis of each downstream coolant passage is offset from the central region of the coolant chamber whereby coolant flows into each one of the downstream coolant passages in a tangential fashion; and wherein the coolant chamber is defined by a coolant chamber wall wherein at least a portion of the coolant chamber wall is a generally arcuate wall portion that redirects coolant flowing into the coolant chamber so as to directly enter each one of the downstream coolant passages.
