ABSTRACT:
A tool holder (10) in which coolant fluid is delivered to a driven tool (115) through a piston (220) which extends through an axial passage in the tool holder (10) and its collet or chuck (170) and is held in contact with the tool (115) by pressure of the coolant fluid. The tool holder advantageously provides an axial float in which springs mount the tool (115) to the tool holder (10) and allow the collet to follow the lead of the tool. The coolant delivery system (200), although acting in an axial direction, does not interfere with the axial "float" of the tool and collet, as the fluid pressure is chosen to be great enough to provide a face seal and small enough not to destroy the float of the tool.
