Abstract
A method of manufacturing a steel bodied bit is shown in which a hardfacing of a highly conformable metal cloth containing hard, wear resistant particles is applied to the bit face as well as to the interior of the bit nozzle openings. By hardfacing the nozzle openings, fluid erosion in the region of the openings is eliminated.
