Polycrystalline diamond compact (PDC) cuttersenhance the performance of drill bits, making them dynamically stable across awide range of demanding vertical and directional drillingapplications.
Our PDC bits are made to compete not only infaster penetration rates, but priced to ensure your cost per foot will be one ofthe lowest in the field.
Bits are available in 3 blade, 4 blade5blade, 6 blade 7 blade, 8 blade, and other custom designs asrequired.

Main Features of PDC bit:
1) ThePDC rock bit is suitable for soft to medium soft formations.
2)structure is force balanced, bit blade is asymmetrically designed, and spiralblade and spiral gage are also designed so that the load on bit is balanced thatresulting better stability of the bit.
3)Multiple typesof high performance PDC cutter are strategically arranged on the bit forimproved service life the bit.
4)Shock absorbers are designed to make the bit capable of drilling throughformations with hard stringers.
5)Hydraulic system of the bit is optimized using dynamic flow pattern simulationtechnology to enhance cleaning and cooling effects of the bit to effectivelyprevent bit from balling.
6)Erosion on bit surface is effectively prevented by utilizing hardfacing materialof highly erosion resistant and applying advanced base metal enhancementtechnology.
7) Ports on bit are also optimally designed to preventerosion of water courses inside the bit.
