  • Patent number: 11633843
    Abstract: A percussion tool is used for performing a chiseling operation on a workpiece with a chisel. The percussion tool comprises a housing including a cylinder portion, a tool holder coupled to the cylinder portion for holding the chisel, and a percussion mechanism including a striker supported for reciprocation in the cylinder portion. The percussion mechanism is configured to impart repeated axial impacts to the chisel with the striker. The percussion tool further comprises a flange between the cylinder portion and the tool holder. Movement of the chisel within the tool holder toward the percussion mechanism is stopped by the flange.
