The barrel is coupled to the barrel coupling portion of the shank. The barrel includes a bit coupling portion configured to couple to a tool bit. The barrel also includes a first depth indicium disposed on a surface of the barrel and a second depth indicium disposed on the surface of the barrel. The second depth indicium is circumferentially spaced about the barrel from the first depth indicium. The sleeve is disposed concentrically about and slidable along the barrel. An edge of the sleeve provides a visual indicator to determine depth based on the first and second depth indicia.
