Abstract
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.
