    Product Description

    The HIGH STRENGTH, HIGH TOUGHNESS CEMENTED CARBIDE BLOCK, combined with the OPTIMIZED number OF block and row, exposure height and SPECIAL-shaped BLOCK, GIVE FULL play to THE high wear resistance and excellent cutting ability of the blade. For the steel bit, the tooth surface is hard-faced with a new wear-resistant material, thus extending the service life of the cutting structure while still maintaining a high ROP.

    Product Advantage

    1. Journal bearing. Hard face head bearing surface. The taper bearing is inlaid with antifriction alloy and then silver plated. The bearing capacity and bite resistance of bearings are greatly improved.

    2, the O-ring is made of high-saturation nitrile rubber with higher wear resistance, which increases the sealing section. The sealing flange in the conical sealing area is precisely designed, which increases the reliability of sealing.

    3. Bit bearing can be ball lock or ring lock. Bits with ring lock bearings can support higher bit weights and bits with ball lock bearings can be used for high-speed drilling.

    4. The full rubber compensator can limit the pressure difference and prevent drilling fluid from entering the lubricating oil system, which provides a good lubrication guarantee for the bearing system.
