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 ,

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.
