2 . Descriptions:

PDC Drill Bit is a higher performance Drill Bit which are used in the oil,mining and water  drilling well . The PDC Drill Bit have different type and size . But all of them are desgined that should be consided the effects as below : 

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

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

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

3. Hybrid Drill Bit Advantage :

• Higher overall ROP: Maintains PDC-equivalent ROP in soft formations while increasing ROP in harder formations that are typically drilled by roller cone bits.
• Lower vibration: The unique design of hybrid bits provides an extremely stable drilling platform that mitigates vibration present in roller cone and PDC environments.
• Better tool face control: Superior directional bit for motor or rotary applications with better tool face control and steer ability than a PDC.
• Improved torque control: hybrid bits offer unrivaled torque management in the toughest formations; even in transition zones torque is controlled with smooth and fast drilling.

4. Material Capacity & Following Standard

The steel materials of PDC Drill Bit is AISI 4145H alloy structural steel .

‌AISI 4145H alloy structural steel‌: This is a steel specifically used for oil drilling tools, especially for the manufacture of heavy-duty drill pipes. AISI 4145H steel has good wear resistance and toughness, can withstand high pressure and high temperature environments, and is suitable for deep and ultra-deep well drilling operations‌45.

7  .PDC Rock Drill Bit  Cutters

Polycrystalline Diamond Composite (PDC) cutters are the main point of contact for a drill bit. PDC bits remove the rock mainly by shearing.

The PDC cutters 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.

8. PDC Rock Drill Bit Nozzles

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.

9 . Steel Body PDC Rock Bits

Steel body is the opposite of matrix body. 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.

10. Manufacture Process :

PDC Cutter Manufacture process

‌The production process of diamond cutting blades mainly includes three methods: sintering diamond cutting blades, welding diamond cutting blades and electroplating diamond cutting blades. ‌

Diamond PDC Cutter Sintering diamond cutting blades‌:

There are two main methods for sintering diamond cutter , namely cold pressing sintering and hot pressing sintering. Both methods fix the diamond particles on the matrix by pressing and sintering. Cold pressing sintering is carried out at a lower temperature, while hot pressing sintering is carried out at a higher temperature and pressure to ensure that the diamond particles are more firmly fixed in the matrix.
