Abstract
A tip for use on an earth working roll for mining, construction and public works machines such as crushers, surface miners, milling machines and the like includes a working end provided with side relief to reduce drag and wearing, require less power to drive the rolls, and lengthen the usable life of the tip. The working end can also have a generally flat front surface to improve the yield in a crushing or other similar operation. The tip includes a base and a wear cap releasably secured together by a retainer.
