Black Epoxy N35-N52 Neodymium Magnet
BOHONG has specialized in the manufacture of PDC for the Oil & Gas drilling industry.
PDC Cutter can be designed and manufactured with customer specifications.
PDC Drill Bits
BOHONG also manufactures PDC dome, conical and chisel cutters. These can be used as impact arrestors for PDC Drill Bits; as cutting structures for roller cone drill bits and down hole hammer/percussion bits; and as gage protection for all drill bits and other downhole tools such as stabilizers, reamers, hole-openers, etc.
