Abstract
A tool bit includes a drive portion configured to be engaged by a tool, a shank extending from the drive portion, and a tip coupled to an end of the shank opposite from the drive portion. The tip has a compressive residual stress layer formed by laser ablating the tip with a laser beam to increase a wear resistance of the tip relative to the shank.
