Abstract

In such fields as road milling, mining and trenching it is often desirable to engage and degrade tough materials such as asphalt, concrete and rock. To do so, degradation picks comprising hardened tips may be secured to an exterior of a rotatable drum so as to be repeatedly brought into contact with a surface of a material to be degraded. To secure such degradation picks to the rotatable drum, a toroidal body comprising an interior surface rigidly attachable to the rotatable body and an exterior surface comprising a plurality of bore holes disposed there around may receive a plurality of degradation picks secured within the bore holes.
