The Advantages of single cone bit

1. Single cone bit is a bit slow, that cone drill bit of speed than the speed of smaller, mainly chaotic cutting rock, suitable for high-speed, high pressure drilling wells sidetracking the old, old wells deepened so slim hole drilling.
Applications more widely applicable not only to lateral drilling, and can be used in deep wells.

2. Working torque than the PDC drill bit in the same conditions of pressure and lower strata can reduce the problem of small size drill expansion button to avoid mine accidents.

3. Single cone bit with both three-cone bit and PDC bit of advantage, there is a difference between the two Surrounded by a shortage of more than three-cone bit more suitable for large plastic formation, but also can be applied to PDC bit difficult to deal with hard interlayer, and other complex formations.
4. With the downhole drill motor to achieve high speed and special drilling needs.
5. Size: various sizes 5 7/8"-17 1/2"

Extremely high quality tungsten carbide

High effectively cutting ability abd strong anti-breaking ability , which can increase ROP and improve service life of bit effectively

metal sealed journal bearing extend cutter

The bit can achieve longer service life and higher reliability.

2. Air Cooling Roller Bearing Steel Tooth Bit
Cutting Structure:The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit
Gauge Structure:Gauge protection with gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability.
Sealed Bearing Structure:Air cooling roller bearing package. Balls lock the conewhich reduces the probability of cone-dropping to minimum.
Main Type Available:Size: 5 7/8",6",6 1/2",7 1/2",7 7/8",8 1/2",9 1/2",9 5/8",9 7/8",12 1/4",14 3/4",17 1/2", etc.
IADC Code:1-- Series, 2-- Series, 3-Series
3. Non-Sealed Roller Bearing Steel Tooth Bit
Cutting Structure: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 Cdropping to minimum
