Features
1.Sizes:3 3/4" (95.3mm)~26" (660.4mm)
2. tungsten carbide insert tricone bit
3. Cover all all IADC code
3. Cover all all IADC code
4. certified by ISO,API
5.high quality and low price
6.high efficiency
Advantages
1.Suitable for medium to medium hard formation of high Crushing Resistance
(hard shale,sands,etc.)
2.Bit bearing is non-sealed roller bearing.
3.Hardfacing is applied on the shirttail,and carbide inserts for gage protection
are pressed into the head OD.
4.Cone gage surface is reinforce with carbide compacts.
5. Partial top spoon shaped inner row of teeth, the wedge outer row of teeth is not equidistant
teeth, in the back cone tooth and the outer row of teeth between adds a row of trimming gear
6. High compressive strength, hard and abrasive high formation, such as limestone, dolomite,
sandstone, chert and other
7.Cone bit to adapt to the soft, medium and hard of various strata.
8.Hours in the rotary cone bit with the impact, crushing and shearing the role of broken rock.
9.Reasonable price and long working life.
