Product Desciption
Advantages:
1. The impact resistance of the teeth is improved and the tooth breaking rate is reduced by adopting the high strength and toughness cemented carbide teeth;
2. The optimized design of tooth row number, tooth number, bared tooth height and unique alloy tooth shape give full play to the cutting ability and cutting speed of the bit;
3. Roller cone bits locked with circlips can bear high drilling pressure;
4. The anti-friction alloy is welded in the inner hole of the roller bit to improve the anti-occlusion ability of the bearing;
5. The optimized sealing compression of O-ring of NBR improves the reliability of bearing sealing;
6. The all rubber oil storage bag which can limit the pressure difference and prevent drilling fluid from entering the lubrication system is adopted to provide good lubrication for the bearing system, and ensure the normal operation of "O" ring and improve the working life of the roller bit;
7. The new grease with high temperature resistance and low wear is adopted to improve the high temperature resistance of the sealing lubrication system of the roller bit.
Parameter:
Roller cone bit types as below:
Roller cone bit is one of the most widely used drilling bits, adapting to a variety of formations from soft to hard.
According to the number of teeth, it can be divided into single cone bit, three cone bit and assembling multi cone bit.
According to the cutting material, it can be divided into steel teeth (milling teeth) and tooth setting bit.
The tooth shape of roller bit is different for different formations:
(1) Soft rock stratum -------- big teeth roller bit, IADC 417 or 437
(2) Medium hard formation -------- medium teeth roller bit, IADC 537 or 617
(3) Extremely hard formation -------- small teeth roller bit, IADC 637 / 737 / 837

Shipment and package of roller cone bits:
1, Characteristics of roller bit core barrel construction:
1). It is easy to operate and adapted widely. It can be drilled without circulation or with reverse circulation. After short-term training, the workers can master the operation methods.
2).This kind of technology can break the rock evenly with high efficiency, low cost and good piling quality.
2,Application
This method is suitable for the construction of rock socketed piling with diameter less than φ 1500mm and flat rock surface.
3,Principle of construction
1). When the roller wheel is working at the bottom of the hole, it is not only rotating around the kelly bar, but also around the center axis of the roller wheel. The rotation is carried out in rolling form, with small running resistance, so it can bear large drilling pressure.
2). When the roller bit contacts the rock at the bottom of the hole, the contact area between the alloy tooth on the roller bit and the rock is small (contact with the supporting point), and it is easy to obtain higher unit axial pressure, so as to crush the rock.
3). When the roller bit is rotating at the bottom of the hole, it is not only under the axial pressure of the kelly bar, but also by the impact load caused by the change of the central height of the cone during the rotation, which improves the effect of rock crushing.
4). when the tooth is rolling at the bottom of the hole, the carbide teeth alternately work to break the rock on by one. Each carbide tooth work for a short time with low wear, which is conducive to improving the life of the roller bit.
4,Warm tips for construction:
1). When the alloy bit meets the strongly weathered rock or hard rock, the alloy drill bit can be replaced with a suitable cone bit.
2). After the bit is lifted up, the muck and sediment in the bucket shall be removed in time, and the roller wheel, support point and flange plate shall be checked. If any damage, it shall be repaired for use in time
