Product Description
PDC Drill Bit 
Product Description
Diamond compact (PDC) drill bit take PDC as main cutting elements, suitable for soft - medium hard formation drilling, and have better advantage when drilling in incomplete formation. 
PDC drill bit can be divided into PDC core drill bit and PDC non core drill bit (including anchor bits) and so on. 
Our company PDC drill bit have advantage of high wear resistance and high impact resistance, good stability, long using life, high drilling efficiency, low pressure and medium speed drilling, good gage effect, using in a wide range, cost-effective and has excellent characteristics, can be widely used in geological exploration, coal mining, water conservancy hydropower construction, highway and railway construction of the building, rock drilling and rock sampling and pumping test piles. 
And we can make production according to customer's requirements and geological conditions to overcome the special formations dedicated. 

Function Characteristics:
1/ longer using life: take PDC inserts as main cutters, it's using life is 10 times more than carbide, 4 to 5 times of normal diamond drill bit. 
2/ high drilling efficiency: large outcropping of diamond (composite polycrystal line layer almost entirely exposed), the drill can remain very sharp all the time, thus greatly improving the speed of the drill. 
3/ can make drilling in low pressure, low rotary speed, and broke rock through scratch and cutting, pressure of drilling just need 1/3 of impregnated diamond core drill bit in same diameter. 
4/ Excellent gage effect: our company PDC drill bit be mounted with polycrystalline diamond inside and outside to make good gage, good wear resistance, guaranteed good gage performance, make efficient usig of the cutting teeth. 
5/ Due to the high drilling speed, long using life, thus drilling costs are greatly reduced, cost effective. 
6/ widely used range suitable carbonate rock, limestone, chalk, clay, siltstone, sandstone and other soft, medium and hard (can drill rock below 9 degree) stratigraphic drilling, compared to normal drill bit, especially drilling of 6-8 degree, the effect is particularly significant. 

Models:
1/
PDC non core drill bit: fast footage, high-strength abrasion resistance, good stability and universality, apply to soft and hard rock. 
Specifications: ϕ56, ϕ60, ϕ75, ϕ94, ϕ113, ϕ133, ϕ153, ϕ185


2/
PDC core drill bit: fast cutting footage, long using life, good in rowing powder, high efficiency in coring, suitable for soft to medium hard rock. Rock grade 2-10 grade, suitable formation: sandstone, limestone, schist, hematite rocks. 
Common specifications: ϕ60, ϕ75, ϕ91, ϕ94, ϕ113, ϕ133, ϕ153, ϕ185



3/
PDC three wings drill bit: This drill bit is a newly developed, high efficiency in soft rock drilling, suitable hole openings and fast footage, which can meet the need of large diameter drilling. Used in rocks grade 1-6 levels. Suitable formation: mudstone, soft shale, soft sandstone. 
Common specifications: ϕ94, ϕ113, ϕ133, ϕ153, ϕ185
