How PDC Cutters are made

PDC Cutters
The invention of the PDC cutter propelled the fixed cutter to the forefront of the drilling industry and the idea instantly took
off. Because the shearing action of PDC cutters are more efficient than the crushing action of a button or tooth bit, fixed
cutters are in high demand.
In 1982, PDC drill bits accounted for only 2% of total footage drilled. In 2010, 65% of total footage drilled was by PDCs.

Applications
The diamond drill bit is used in nearly all applications including geothermal energy drilling, mining, water well and natural gas
drilling and oil well drilling. Total depths range from 100′ to 20,000′.
PDC drill bits are used extensively in natural gas drilling.

Limitations
Impact damage, heat damage and abrasive wear all inhibit a drill bit’s performance and can occur in even the softest geological
formations. However, the most difficult formation for a PDC bit to drill are extremely abrasive ones.
With PDC popularity on the rise, bit manufacturing companies are seeking new materials and design aspects to make a tougher bit
without compromising ROP.

How PDC Cutters are made
Cutters are made using a combination of high heat and high pressure. Man made diamonds can be grown in 5-10 minutes. Because of
this diamond content, a fixed cutter bit may also be known as a diamond drill bit.
High heat plus pressure creates a PDC (polycrystalline diamond compact) cutter.
Cutters are made from a carbide substrate and diamond grit. High heatof around 2800 degrees and high pressure of approximately
1,000,000 psi forms the compact. A cobalt alloy is also present and acts as a catalyst to the sintering process. The cobalt helps
bond the carbide and diamond.
During the cooling process, the tungsten carbide shrinks at a rate of 2.5 times faster than the diamond. Controlling this stress,
as with most aspects of drill bit design, is called Intellectual Property, and manufacturers rarely, if ever, share their secrets.

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.
