Advantage
1.High-strength, high flexibility, high temperature, high wear resistance.
2. High-precision metal seal.
3. Locking roller ball, to adapt to high-speed.
4. The use of high strength high toughness carbide teeth,
5. Hours in the rotary cone bit with the impact, crushing and shearing the role of broken rock.
6. Cone bit to adapt to the soft, medium and hard of various strata.
7. Reasonable price and long working life.

Recommended Drilling Parameter
IADC | WOB (KN/mm) | RPM (r/min) | Applicable Formations | |
111 | 0.3~0.75 | 200~80 | Very soft formations with low compressive strength and high drillability, such as clay, mudstone, chalk, etc. | |
121 | 0.3~0.85 | 200~80 | Soft formations with low compressive strength and high drillability, such as mudstone, gypsum, salt, soft limestone, etc. | |
131 | 0.3~0.95 | 180~80 | Soft to medium formations with low compressive strength and high drillability, such as medium soft shale, hard gypsum, medium soft limestone, medium soft sandstone, soft formation with harder interbed, etc. | |
211 | 0.35~0.95 | 180~80 | Medium formations with high compress strength, such as medium soft shale, hard gypsum , medium soft limestone, medium soft sandstone, soft formation with harder interbed, etc. | |
241 | 0.35~0.95 | 180~70 | Medium hard formations with high compressive strength, such as abrasive shale, limestone, sandstone, dolomite, hard gypsum, marble,etc | |
321 | 0.4~1.0 | 150~70 | Hard semi-abrasive formations, such as abrasive shale,limestone,sand stone,dolomite,hard gypsum, marble,etc. | |
