Toolholder coupling for high pressure coolant

摘要

A coolant coupling system for coupling a toolholder (10) to a toolholder support member (15), wherein the shank (35) of the toolholder (10) is secured within the bore (65) of the toolholder support member (15) with an interference fit and a coolant channel (120) extends through the toolholder support member (15) to the toolholder (10) passing through the region of the interference fit to provide a high pressure seal for the coolant passageway (105, 125) between the toolholder (10) and the toolholder support member (15).
