Charateristic:
1>PDC and roller optimum matching, the bits has higher adaptability and rock breaking effciency in hard drilling stratum.
2>Compound cutting structure force balance optimization, consideration be given to working stable and layer adaptability to increase service life.
Rock Reamer or Hole Opener.
