1. A tool bit connectable to a tool, the tool bit comprising:
a working end portion;
an insertion end portion defining a first profile and having an outer surface formed on the insertion end portion, the insertion end portion defining an end of the tool bit and configured to be coupled to the tool;
a non-circular profile formed on the tool bit and partially defining the outer surface; and
an alignment region positioned between the non-circular profile and the end of the tool bit, the alignment region partially defining the outer surface and including projections that gradually transition from the first profile to the non-circular profile to facilitate alignment of the non-circular profile with the tool.
