Hydraulic System 8 3/4 Inch PDC Core Bits

Hydraulic System 8 3/4 Inch PDC Core Bits

Product Description

1. The bit is suitable for soft to medium soft formations.

2. Cutting structure is force balanced, bit blade is asymmetrically designed, and spiral blade and spiral gage

are also designed so that the load on bit is balanced that resulting better stability of the bit.

3. Multiple types of high performance PDC cutter are strategically arranged on the bit for improved

service life the bit.

4. Shock absorbers are designed to make the bit capable of drilling through formations with hard stringers.

5. Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance

cleaning and cooling effects of the bit to effectively prevent bit from balling.

6. Erosion on bit surface is effectively prevented by utilizing hardfacing material of highly erosion resistant

and applying advanced base metal enhancement technology.

7. Ports on bit are also optimally designed to prevent erosion of water courses inside the bit.
