  • Publication number: 20200123858
    Abstract: A downhole tool includes a blade coupled to a body. The body and blade rotate about a longitudinal axis. A pre-formed faceplate is connected to the blade and partially defines a cutter pocket therein. Another portion of the cutter pocket is defined by the blade. The cutter pocket includes a sidewall and a base, with the sidewall formed by the blade and the pre-formed faceplate, and the base formed by the blade. The pre-formed faceplate includes a pre-formed hardfacing element. A downhole tool includes a blade coupled to a body. The body and blade rotate about a longitudinal axis. A pre-formed segment is connected to the blade and has a cutter pocket therein. The cutter pocket includes a sidewall and a base, and a cutting element is coupled to the pre-formed segment and within the cutter pocket.
