Product description:
******7(very soft : soft marl, clays , sands ,salts)
The ******7 bits are used to drill low-compressive strength , soft formation.. wear-resistant hard facing is used to control tooth wear , on the softest bits type this hard facing completely covers the bit teeth.
******7(soft: clays, soft shale , marl, sands, salts )
The ******7 bits are used to drill high-compressive strength , medium hard formations.
******7(medium soft: shale , marl , sandstone , soft limestone)
******7(medium: hard shale , limestone , medium/hard sandstone)

1. Journal bearing. Hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver-plated. The load capacity and seizure resistance of the bearing is greatly improved.
2. O ring seal is made of the more wear resistance high saturated buna-N with the increased seal section and precisely designed sealing flange in the cone sealing area increased the reliability of the seal.
3. The bit bearing can be ball locked or ring locked. Bit with ring lock bearing can stand high weight on bit and bit with ball lock bearing can be applied to high rotary speed drilling.
4. New type of grease that can sustain high temperature up to **0°C is utilized.
5. High wear resistance and excellent cutting ability of the insert bit are given full play by using carbide compacts of high strength and high toughness in combination with optimized compact numbers and rows, the exposure height and special shaped compacts. For steel tooth bit, the tooth surface is hardfaced with new type of wear resistant material and thus extended working life of the cutting structure while still maintaining high ROP.
