Abstract
A seal of a tool of a breaking hammer, a sealing arrangement, a breaking hammer and a method of sealing a tool of breaking hammer is provided. The seal is a sealing ring having an outer periphery provided with several projecting elements, which are slanted. The projecting elements generate torque in the sealing ring when being pushed in a transverse direction during use of the breaking hammer. Thus, the sealing ring may rotate relative to the tool.
