A grooving tool includes a spindle rotatable about a longitudinal axis thereof and having at least one coolant inlet port, a ramp portion, and a fluid flow path to the ramp portion; a tool bit moveably coupled to the ramped portion, the tool bit comprising one or more teeth and one or more coolant channels to supply coolant proximate the one or more teeth, the one or more coolant channels operatively connected to the fluid flow path; wherein movement of the tool bit along the ramp portion toward the inlet port causes the one or more teeth to be displaced outward from the longitudinal axis. The fluid flow path may include a longitudinal passage in the spindle disposed generally along the longitudinal axis. The coolant channels may be angled with respect to the teeth and dispense coolant supplied via the fluid flow path toward the teeth.
