A conical bit penetrator pocket protector for earth displacement equipment for maximizing penetration into hard rock during trenching, drilling, mining, or boring operations. The bit penetrator pocket protector for earth displacement equipment includes a body which defines an upper bit end and a lower shank end. The upper bit end defines a bit insert opening configured to detachably accept a penetrator bit tip. The lower shank end is configured to be securable to a penetrator holder that is welded to an implement of earth working equipment such as trenching equipment, rock saw equipment and/or a rotatable drum, or the like. A flange, or pocket protector, is defined between the upper and lower ends in order to provide protection for the bit penetrator lower end and a holder in which it is received by minimizing rock and earth fines from contacting and building up between the holder and bit penetrator. Further, the flange acts as a load bearing surface between the bit penetrator and the holder, thereby protecting the lower end of the bit penetrator and the full face of the holder.
