Drill bit with prefabricated cuttings splitter and method of making

Abstract

A method of making a drill bit for drilling subterranean formations includes, forming a bit mold having at least one recess receptive of a distal portion of a prefabricated splitter, positioning the distal portion into one of the at least one recess, and filling the bit mold with at least one material.

1 . A method of making a drill bit for drilling subterranean formations, comprising:
 forming a bit mold having at least one recess receptive of a distal portion of a prefabricated splitter;   positioning the distal portion into one of the at least one recess; and   filling the bit mold with at least one material.   
     
     
         2 . The method of making the drill bit for drilling subterranean formations of  claim 1 , further comprising positioning a proximal portion of the prefabricated splitter into a volume of the bit mold that is to be filled with the at least one material to form a body of the drill bit. 
     
     
         3 . The method of making the drill bit for drilling subterranean formations of  claim 2 , further comprising bonding the proximal portion of the at least one splitter to the at least one material. 
     
     
         4 . The method of making the drill bit for drilling subterranean formations of  claim 1 , further comprising shaping the prefabricated splitter so that a dimension receded deeper within the body is greater than a dimension receded more shallow within the body to thereby mechanically lock the splitter into the body. 
     
     
         5 . The method of making the drill bit for drilling subterranean formations of  claim 1 , further comprising heating the at least one material to sinter it into the drill bit. 
     
     
         6 . The method of making the drill bit for drilling subterranean formations of  claim 1 , wherein a material of the at least one prefabricated splitter is different than the at least one material.
