ABSTRACT:
A degradation assembly for use with a driving mechanism includes a working portion coupled to a shank assembly. The working portion has an impact tip brazed to a working end of a carbide extension. The carbide extension has a cavity formed in a base end that is adapted to engage with a shank and a locking mechanism of the shank assembly. The shank has an outer surface proximate a first end which is receivable within the cavity of the carbide extension. The locking mechanism has a radially extending catch configured to engage with the cavity and couple the shank assembly to the working portion. The shank has an outer surface proximate a second end which is adapted to be press-fitted within a recess of a driving mechanism.
