ABSTRACT:
A pneumatically driven impact type of descaler tool includes a manually gripped housing having a rear portion of generally circular cross-section which includes therein a pneumatically driven reciprocating piston assembly which acts as a hammer and a right angled forward portion having a forwardly tapered nose which is particularly adapted for fitting into corners of a workspace. A pivoted solid arcuate body shaped in the form of a quarter circle forms an anvil. A descaling head is secured to the lower end of the anvil and is adapted to be actuated at the other end by the piston assembly which imparts a srelatively strong repetitive impact motion to the descaling head when held against a metal work surface.
