Cutting tool assembly with replaceable spray nozzle

A cutting tool assembly includes a support block having a concealable outer surface portion, first and second bores, and first and second fluid passages. The first fluid passage is in fluid communication with the first bore and the second fluid passage. The second fluid passage has an axis and extends between the concealable outer surface portion and the second bore. Furthermore, the second bore and the second fluid passage are configured such that the axis may be extended through the second bore and beyond the support block without intersecting the support block. The cutting tool assembly also includes a replaceable spray nozzle having a body that extends into the first bore such that the spray nozzle is in fluid communication with the first fluid passage.
