摘要： A rock bit is formed with pockets for enhanced cutting element retention and support of cutting elements during operation of the rock bit. Portions of the pockets are carburized to increase a yield strength of the pockets, which also increases the retention of the cutting elements. The pockets are formed at a diameter that is slightly smaller than an outer diameter of the cutting elements. Portions of the pockets are then carburized. The pockets are heated until the diameter of the pockets is equal to the outer diameter of the cutting elements. After the rock bit has been cooled and cleaned, a material is placed in each pocket prior to installing the cutting elements. The material homogenizes support for the cutting elements during operation of the rock bit.
