Abstract
A tool bit including a drive portion, a tip, and a body. The drive portion is disposed at a first end of the tool bit and is configured to be coupled to a tool. The tip is disposed at a second end of the tool bit opposite from the drive portion. The tip includes a target region treated by laser peening. The target region is spaced from an end of the tip. The body extends between the drive portion and the tip.

A tool bit comprising:
- a drive portion disposed at a first end of the tool bit and configured to be coupled to a tool;
- a tip disposed at a second end of the tool bit opposite from the drive portion, the tip including a target region having a first grain structure that is modified by laser peening and a surrounding area having a second grain structure that is not modified by laser peening, the surrounding area located between the target region and the drive portion and between the target region and an end of the tip, the target region providing tensile stress on the surrounding area, the surrounding area providing compressive stress on the target region;
- and
- a body extending between the drive portion and the tip.
