Products Description
4 wing PDC Drag bit for water well drilling
The product advantages of water well PDC Drag bits mainly include the following aspects:
1. Made of high-grade polycrystalline diamond compact, high-quality drilling body material and optimized drilling body
structure, featuring wear-resistance, high drilling efficiency and long service life.
2. If the rock hardness is divided into 12 grades, the PDC drag bit is suitable for drilling soft to medium hard formations from
1 to 6, such as: mud formation, loose rock formation, regolith layer, shale, medium hard limestone, marble, etc
3. Common Specification: φ75/91/113/133/153/171/200/220/245/275/325mm and other diameter are available
4. Common thread: 42/50/60/73/76/89, all kinds of thread are available

Factory price 56mm 98mm 146mm 152 mm oil drilling tools diamond pdc drill bit Used in geological exploration drilling holes, gas drainage hole, grouting hole drilling, suitable for easy soft rock and medium hard rock.
Available sizes : 50mm, 56mm, 60mm, 65mm, 75mm, 94mm, 98mm, 113mm, 120mm, 120.5mm, 124mm, 143mm, 149mm, 152mm, 173mm, 190.5mm, 203mm, 254mm. Wireline core bit : A gauge, B guage, N gauge, H gauge , P gauge. 1.Suitable for soft, medium and hard formations.
2.Super strong material promotes gauge wear resistance to provide long bit life. 3.The cutter's back rake has been unique design, reducing the bit torque and increasing aggressiveness. 4.Cuttings removal and bit cooling for bits are optimized by matching the volume of rock removed by the cutter on each blade with the proportional fluid flow. Non-coring PDC drill bit uses PDC as main cutting components, with the excellent wear-ability and impact toughness of the PDC. It has a useful life, high-efficiency, and good performance cost ratio.

Diamond compact (PDC) coreless bit refers to a bit with diamond compact as cutting edge, which has the advantages of high strength, high wear resistance and impact resistance. The main categories are: composite bit for geological exploration, which is mainly used for geological exploration and is suitable for soft to medium hard rock layers; Coalfield drilling adopts composite bit, which is mainly used for coal seam drilling and excavation in coal mines. Generally speaking, the rock stratum in coalfield is relatively soft, and composite bit is widely used, such as anchor bit and three-wing bit; Composite bit for oil exploration is mainly used in oil and gas field drilling. Composite bit for oil field has the highest cost and the highest quality requirement among all composite bits, and has different quality requirements and standards at home and abroad.

New wear-resistant material is applied tothe surface of the steel teeth , which canimprove the cutting life of the bit whilemaintaining the high mechanical drilling speed.
Based on rock mechanics features tooptimize cutter row arrangement andnumber of cutter. then the cuttingefficiency and ROP can also be improved.

FAQ
1.The Quality of Drill bit?
We have many series of rock bits,quality grades and prices are different.We believe that the proper tools with higher cost-performance is the most impormant.For example,our top quality rock bits is not cost-effective for water well drilling,as the water well drilling machine can not drive the super rock bit to perform their best.but for very deep well drilling high quality grades rock bits is cost effective even its price is much higher.So it is better tell us as more as possible the details of projects,then we provide the proper solutions and offer,usually 2 or 3 solutions wil be provided for options.
2.Trade Assurance
Answers:we have joined the Trade Assurance on Alibaba to protect your payment to make sure that we deliver on time and manufacture quality products as required.
3.How to send inquiry?
It is better send us detailed specificaltions of products,it is better attaching some photos for better understanding.If you are not experienced on drilling fields,for example,many customers don't know IADC code,please feel free,jusst tell us the applications like oil/gas/geothermal/HDD/ware/mining,depth of well,average hardness of rocks,then we will advise suggestions and solutions.You can:-Send us inquiry from Alibaba.com platform.-Send email to us directly or talk on Skype or Whatsapp,salespersons are always waitting for service in working days,and all the inquiries can be replied within 10 hours.
