Diamond Bit 8.5 Inch PDC Core Drill Bit Of Surface Set Bits For
Medium Hard Formation
Description :
There are six different types of core bits that can be
manufactured, depending on the application area and the cutting
media used on the core bits:
- Impregnated Diamond Type
- Surface set Diamond Type
- Tungsten Carbide Type
- PDC Type
- PCD Type
- Electroplated Diamond Type
Overall drilling system typically consists of drill rods, core
bits, reaming shells, core barrels, and drilling rig.
Specification:
- For medium to hard and dense formations such as shale, mudstone,
limestone, sandstone, dolomite, anhydrite, siltstone, and mudstone.
- Cubic TSD cutters 1/8 x 1/8 x 1/8 in³.
- Double cone profile with sharp nose and tapered flank.
- Natural diamond gages.
- Tungsten carbide bit body.
- Feeder/Collector fluid course.
3. Bit profile.
Core PDC drill Bit has a shallow parabolic profile and medium
cutter density, designed for coring the medium hard
formation . Utilizing different patented PDC cutters enhance the
bit’s ability to drill in hard formations.
High quality TSP in the inner blade and gauge has high
wear-resistant for longer bit life.The uniquenozzle design improved
the cleaning and cooling ,enhanced the ability cuttings evacuation.
