Drag bit is a common which used to rework operation ,for drilling cement plug and sinker drilling sand bridge, salt bridge, scraping off the dirt of casing wall and hard wax and some mineral crystallization. Still can scraping well hole,making the wall bright and clean ,it may used to drilling ahead in bushing and side track or drilling and rubbing the mat of perforating shell,etc.
under drilling and pressure effect, drilled goods as the cement is sucked at the bottom, through the rotation, the part of sucked is cutting in the direction of circumference , it will be drilling down gradually .Side lobe milled by drilling goods,forming cylinder space so that better dressing the well bore by drilling.
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.
Stratum conditions
PDC drill bits is mainly used for drilling soft and medium -hard formation. Such as mud stone, limestone, shale, sandstone and granite etc.
Application:
PDC drill bits are used to penetrate the degassing hole, drain hole, and grouting hole of coal mine, water conservancy and hydropower, road construction, bridge and building.
Operatingcondition:
PDC bits work under low drilling pressure, medium-low drive speed, and big drainage.
Availablesize:
50mm, 56mm, 60mm, 65mm, 75mm, 94mm, 98mm, 113mm, 120mm, 120.5mm, 124mm, 143mm, 149mm, 152mm, 173mm, 190.5mm, 203mm, 254mm
Standard Sizes for Immediate Availability: 2" to 8 1/2" (51mm to 215.9mm)
Other sizes available upon request

Certifacte and Factory
Matrix body PDC bits are primarily used for these applications:
- Soft to medium-hard formations
- High volume
- High sand
- Applications where the same bit will need to be used for several bit runs
The strength and ductility of steel give steel-bit bodies high resistance to impact loading. 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.
Steel body PDC bits are primarily used for these applications:
- Drilling in shale formations
- Soft limestone sites
- Fast drilling in the stratum
- Natural gas drilling
- Deep wells
- Abrasive formations
Designed for higher ROP in drilling deep and medium-hard rocks,PDC drill bits always drills from ground to bottom directly without changing another drill bit, it will save huge drilling and laobur cost.
Different from tricone bits, the PDC drill bits need lower WOB but higher RPM,so it always works with mud motor to get high rotating speed.
* Other types and sizes could be designed and manufactured according to the specific requirments.
