Mining Machinery

（一）PDC bit features:
1.Sizes rang from 3 7/8 -26
2.Cover all all IADC code
3.Reliable quality and best price
4.certified by ISO,API
5.long working life

（二）PDC bit Advantages:
1. Short parabolic crown profile, medium cutter density.
2. Interchangeable screw nozzle.
3. Structured diamond/carbide interface. Cutter delays the onset of Fracturing and cutter wear.
4. Under-cut shank maximizes junk slot area for better bit cleaning. Hign filt nozzles for improved hydraulics and Rop.
5. Can be used on rotary or down hole motor.
6. Surfable for soft to medium formation.

（三）PDC bit More information:
1) Be used for water well, oil field, underground, construction, geothermal, directional boring
2) Various of model and dimension available
3) High quality and competitive price
4) Improved support and retention, diamond are impregnated in the matrix behind the PDC
cutters
5) Hejian Ruida petroleum materials Co., Ltd specializes in drill bits, tricone bits, PDC bits bit size range from 3 7/8& quot;to 26& quot;, cover most of IADC codes.

（四）Introduction of PDC (Polycrystalline Diamond Compact):
PDC is made of diamond micro-powder and hard alloy substrate under high temperature and
high pressure. It possess of high wear resistance like diamond, at the same time the impact
resistance like hard alloy and that’s made it the best material as a drill bit cutter. Reinforced PDC
has higher dense diamond powder, claw hard alloy substrate made the two layers solidas whole one. So, the reinforced PDC of supper wear resistance, longer service life and high efficiency.
