Abstract
A tip assembly includes a tip having a nose portion. The tip defines a central bore. The nose portion includes a lip portion and defines a counterbore. The counterbore has a counterbore side wall and a seat surface. The counterbore is contiguous with the central bore. An insert member includes an inner surface, an outer surface and a side wall. The inner surface is opposite the outer surface. The side wall interconnects the inner surface and the outer surface. The insert defines a central aperture that extends from the inner surface to the outer surface. The insert is disposed within the counterbore such that the central aperture is substantially concentric with the central bore of the tip. The lip portion of the tip engages the outer surface of the insert.
