| 发明名称 | Method of manufacturing a tool bit | ||
| 摘要 | A method of manufacturing a tool bit includes machining a working end into a piece of hexagonal bar stock. A shank adjacent the working end is machined, leaving a hexagonal drive portion adjacent the shank. The tool bit is heat treated, and a coating is applied to the working end, the shank, and the hexagonal drive portion of the tool bit to inhibit corrosion of the tool bit. At least a portion of the shank is polished to remove the coating from the portion of the shank. | ||
