PDC (polycrystalline diamond compact) bits are made up of a steel body with a series of PDC cutters attached to the surface.  The cutters are made of tiny diamond particles that are bonded together under high pressure and high temperature to form a hard, durable material. The cutters are typically arranged in a specific pattern on the surface of the bit to provide optimal cutting action and efficiency.

 

The cutting action of the PDC bit is achieved through a combination of shear and crushing forces. The cutters scrape along the bottom of the wellbore, grinding away the rock to create a hole. As the bit rotates, the PDC cutters penetrate the rock, and the weight of the drill string pushes the bit into the formation, generating a crushing force that breaks up the rock.

 

Our PDC bits design features as following:

 

Cutter shape and size: flat or dome PDC cutters. Sizes have 1304, 1308, 1313, 1613 etc.

 

Cutter arrangement: various arrangement on 3-blade, 5-blade, 6-blade, and the protection caliber. Each cutter has its different side angle.

 

Bit profile: long parabolic and short parabolic design.

 

Hydraulic design: big center flush hole or the multi-flush hole

 

PDC bits have several advantages:

1, longer lifespan

2, faster penetration rates

3, higher drilling efficiency and lower drilling costs

 

PDC bits could be used in medium hard to hard formations like Shale,Limestone,Sandstone etc. Specific applications:

1,PDC bits are used in mining operations to drill blast holes and exploration holes.

2,PDC bits are used in geothermal drilling to drill wells for geothermal energy production.

3,PDC bits are used in construction applications for drilling foundations, tunnels, and other infrastructure projects.

4,PDC bits are used in water well drilling to drill wells for domestic and industrial water supply.
