Produce Different Sizes Of Single Roller Cone Bits For Mining
Industry
1.Carbide inserts are arranged on top of the cine of single cone
bit to improve wear resistance for longer working life of the bit.
2. New type of hydraulic system enhances cone and bottom hole
cleaning ability to assure higher ROP of the bit large diameter
active cutting conical spherical inserts are used for gage
protection on bit body, so that the bit has excellent gage holding
and up-reaming abilities.
3. Single cone bit is suitable for slim hole drilling operations
such as reentry and sidetracking operations.
The main parameter of single-cone bit
| Bit size | Std API pin shank (inch) | Nozzle aperture diameter(mm) |
| mm | inch |
| 95.25-104.78 | 3 3/4-4 1/8 | 2 3/8 REG | 8-14 |
| 107.95-117.48 | 4 1/4-4 5/8 | 2 3/8REG 2 7/8REG |
| 120.65 | 4 3/4 | 2 3/8REG 2 7/8 REG |
| 142.88 | 5 5/8-6 1/2 | 3 1/2 REG |
| 190.5 | 7 1/2 | 4 1/2 REG |
Drilling weight and rotary speed size of single-cone bits
| Rock formation | Bit type | Rotary speed(r/min) | Drilling weight(kN/mm) | Pumping weight(Mpa) |
Soft formations with low compressive strength and high drillability | 437-447 | 70-40 | 0.25-0.5 | <10 |
| Soft to medium formations with low compressive strength | 517-617 | 60-40 |
Advantage:
1. Strictly select the material to ensure the reliable quality. Bad
steel and tungsten carbide inserts won't be used.
2. Strictly act according to the ISO9001 standard, and control by
full-scale inspection.
3. Sales and support people are highly trained in the latest rock
drilling technology and can offer you expert advice on what
products will best fit a specific end use application.
