A high-speed cutting handpiece and coolant apparatus of the type useable in dental procedures. The handpiece is of the type employing a fluid delivery conduit to provide fluid to the oral cavity of the patient for cooling and irrigating purposes. The coolant apparatus includes a cartridge having an initially empty inlet chamber and an outlet chamber initially filled with sterile solution.

The cartridge is disposed in interrupting relationship to the fluid delivery conduit such that fluid from a source is introduced into the inlet chamber which displaces the sterile solution to move it through the downstream end of the fluid delivery conduit.
