Multiple Specifications Are Applicable To Exploration Coring Diamond Bits
Introduction to Exploration Coring Diamond Bits
This PDC is sintered at high pressure and high temperature and consists of diamond and strontium. Can be embedded in mining drill bits for drilling medium to high hardness formations.
The special shape and different technology make this PDC have higher drilling speed, it is specially developed and manufactured for geological exploration and mine rock formation coring.
