nozzles: according to your requirement

pdc cutter: 

rotary speed:60-300 rpm

delivery terms:within 3 days after the payment

package: iron boxes. as customers requirements

oem: ok, we can make kinds of pdc bits according to customers' requirements

pdc bitadvantages:

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. 

pdc bit moreinformation:

1) be used for water well, oil field, underground, construction, geothermal, directional boring 
2) various of model and dimension available 
3) high  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"to 26", cover most of iadc codes.

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.
