Product Pictures
      Drag Bits are designed for a variety of applications including seismic exploration, soil sampling, mining and construction.Drag bits are used for drilling in soft to medium formations.
        Step-type drag bits are very effective in drilling soft and unconsolidated material. They are available in a full range of sizes from 3-7/8” to 12-1/4”.The design of step-type drag bits provides for fast drilling penetration and requires only moderate drilling weight for proper operation. A large center flushing hole is incorporated into our design for efficient removal of cuttings.
        Chevron-type drag bits are recommended for drilling in slightly harder and more consolidated materials. Best suited for abrasive conditions, Chevron-type drag bits are also available in a full range of sizes up to 8”.The clean design, use of premium tungsten carbide and rugged construction of these fine drilling tools ensures effective performance in a variety of ground conditions.
 
Product Advantage

1. Cutting structure is force balanced and bit blade is asymmetrically designed so that the load on bit is balanced that resulting better stability of the bit.
2. Main cutter are high performance PDC cutters to insure service life of the bit while improving ROP.
3. Cutter exposure is optimized to insure the oil bit can achieve higher ROP is soft to medium formations.
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.
