Large Drill Bit 17-1/2 Inch PDC Button Bit Of Rock Drilling Tools

1 . Descriptions:

PDC Drill bits is less weight and more RPMs. This well in the HDD industry is where most smaller rigs do not have enough weight capability and tend to rotate too fast. PDC bits also tend to run much smoother than hammers and tricones. A smoother running bit is much easier on the rig itself.

A Polycrystalline Diamond Compact cutter is the heart and sole of a PDC drill bit. It makes up more than 90% of all drill bits used today for mining, geothermal, oil and gas drilling. What are the keys effected the PDC drill function ?

According to the International Association of Drilling Contractors (IADC), the Fixed-cutter bit classification composed of four characters that designate:

• PDC Drill Bit Body material
• PDC Drill Bit Cutter density
• PDC Drill Bit Cutter size or type
• PDC Drill Bit profile

All of our PDC Drill bits are fit for API standard and used in the drilling Industry.

The PDC drill bits size 3~22inch with 3~9Blades are available. And different classification cutter are optional according to your budget .

4 . PDC Drill Bit Of Cutters

Polycrystalline Diamond Composite (PDC) cutters are the main point of contact for a PDC drill bit. PDC Drill bits remove the rock mainly by shearing. The PDC cutters of PDC Drill Bit are exposed to a lot of heating and cooling down the well, a very challenging environment.

PDC cutters that have lower thermal degradation and more thermal stability generally achieve higher ROP and increased wear resistance. So, optimizing the cutter is important.

5. PDC Drill Bit Nozzles

PDC Drill bit nozzles help clear the cutting area and cool the Polycrystalline Diamond Composite (PDC) cutters.

Effective placement of these nozzles along with the angle they are set at plays a critical role on how efficient the drill bit performs.

Fluid channels also complement nozzle placement to improve the clearing of cuttings.

6. Steel Body PDC Bits

Steel body is the opposite of matrix body of PDC Drill Bit . It can of withstanding high impact loads, but is softer and lacks protective features. The strength and ductility of steel give steel-bit bodies high impact resistance.

Steel bodies are considerably stronger than matrix bodies.

A beneficial feature of steel bits is that they can easily be rebuilt a number of times because worn or damaged cutters can be replaced rather easily. This is a particular advantage for operators in low-cost drilling environments.

Polycrystalline diamond compact (PDC) drill bits are different than roller cones in that they are one piece bodies with no moving parts. The fixed-cutters shred the rock, so the bit is able to operate with higher rotation speeds more efficiently in consolidated formations.
