A toolholder assembly and method is provided that comprises an adjustable nozzle assembly for redirecting a liquid coolant stream from a direction generally parallel or slightly oblique with resp ect to the axis of rotation of a workpiece (12) to a direction that is substantially orthogonal with respect to this axis. The nozzle assembly includes a threaded base on one end and a nozzle head (33) on the other, and the threaded base may be screwed into or out of a threaded opening in the toolholder body (3) which communicates with the original coolant passageway in order to adjust the n ozzle head at both a desired angle (A) in a plane orthogonal to the axis of rotation of the workpiece, as well as at a desir ed point along this axis. The nozzle head projects a stream of coolant at the interface (20) between the cutting insert (8) and the w orkpiece regardless of the depth of the cut. |
