A cutting bit has a bit body which has a forward end and a rearward end. The bit body contains a seat at the forward end thereof. The bit body contains a bore intersecting the seat wherein a bore wall defines the bore. A cutting insert is received by the seat wherein the cutting insert presents a side surface facing the bore. A wedge has a generally longitudinal seating surface. The wedge has a support surface opposite to the longitudinal seating surface. The wedge is received within the bore so that the longitudinal seating surface of the wedge contacts the side surface of the cutting insert and for at least a portion of the length of the wedge the entire support surface contacts the bore wall so as to frictionally retain the cutting insert in the seat.

Rotatable cutting bit assembly with wedge-lock retention assembly

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.
