A cutting tool assembly (10) includes a support block (12) and a replaceable spray nozzle housing that can be manually installed onto a support block positioned on a drum in the field. Wherein the support block includes a fluid passage communicating water from a water supply to a fluid passage within the spray nozzle housing. The spray nozzle housing is connected to the support block by welding. The weld joint between the spray nozzle housing and support block forms a liquid tight seal. The spray nozzle housing is oriented on the support block so that water spray from the spray nozzle outlet is directed toward the tip of the cutting tool. |
