Product Description

compound drill bit with rock bit and pdc bit for very hard formation

PDC-roller compound bit is composited by PDC fixed cutting and roller free cutting structure.Rock will be broken by roller teeth's impact crushing. it'll formsbreaking pits on bottom, the uneven surface will weaken rock strenngth. Under roller's helping, the PDC will bites into the layer, the function is obviously on cutting and save work.

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.
3>Bit channel and nozzle compute fluid dynamics(CFD)optimization analysis, to enhance fluid distribution and cleaning/cooling effects.
