Kenclaw Bits-Earth Auger & Parts
1. Cut a variety of formations from clay to medium shale rock. (Up
to 6, 000 psi rock. )
2. Rapid penetration rates, cut as fast as drag bit, is as tough as
a soft formation rock bit.
3. Average cutter life ranges from 500 ft to 2000 ft depending on
4. Suitable for air or fluid drilling.
5. Replaceable bullet cutter to save cost.
6. Available sizes from 3-3/4"(95mm) to 18"(457mm)
We can also produce the kenclaw bits by customers' special
1)certified by ISO9001&API
2)covers all IADC codes
3)size: 3 3/4" (95.3mm)~26" (660.4mm)
4)used for oil well and water well

Design features of this bit
1. The diamond powder is selected in a higher degree.
2. Use a new type of tungsten carbide that different from previous
cutters, it improved the strength character of bonding.
3. The claws of the interface are changed to be net-grooves-shaped
which formed by 10-20 straight vertical grooves, and the depth of
the grooves are shallower.
4. Improved the interior structure of the sintering cell that makes
the pressure and temperature to be more uniform. It is very
important for the PDC sintering.
5. Use new super heat-resistant metal, to avoid being contaminative
6. Amended the sintering processing, and improved the bonding
strength of the diamond-diamond key among the diamond layer.
7. Increase the content of diamond, and increase the thickness of
diamond layer up to 1.5-2.0mm. The result of plenty of tests and
the performance in customers' practical drilling in the oil fields
shown that the performance in heat resistance and impact resistance
are improved evidently, and quite similar to the cutters made by
the best world-class manufactures.

Center nozzle can avoid bit balling, eliminate fluid stagnant area
at bottom hole, increase rising velocity of drilling cuttings, and
improve rop, which is suitable for drilling formations from soft to
middle soft with low compressive strength and high drillability.
Recommended operating parameters
Wob 90 ~ 280(kn)
Ideal wob range 150~220(kn)
Rotary speed 80 ~ 300 (rpm)
Ideal rotary speed range 110~250(rpm)
The above parameters are only for reference. Optimized parameters
are determined by drilling process and lithology of formations on
Very soft with low compressive strength and high drillability, such
as shale, clay, sandstone and conglomerate, etc.
