Product Description
Tricone milled tooth drill bits for drilling granite
Cutting Structure
The durability of premium tungsten carbide insert is improved with new
formulas and new techniques and new techniques. The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing
on the tooth surfaces.
Bearing Structure
Non-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling;
Balls lock the cone which reduces the probability of cone ropping to minimum.
Product Application
It is suitable for the shallow well, water well and geothermal well.
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. | |
