20inch 508mm IADC 115 127 117 milled steel teeth tricone drill bit for clay sandstone

Short Description:

Deris company offers new steel tooth and tungsten carbide insert (tci) tricone bits in sizes from 3 1/2" – 26", with open or sealed bearings, regular or jet circulation, and a wide range of additional custom features for ideal performance in any formation. Tricone bits can be customized to optimize penetration rates and bit life in particular formations and under specific operating weights and rotation speeds.

PRODUCT DETAIL
PRODUCT TAGS

The tricone drill bit is the most popular drilling bit in the world,it can be widely used for Oil&Gas Drilling,Mining,Water
Well,Geological Exploration areas.Our tricone bit divideds into metal sealed drill bit and rubber sealed bit.
1. The jet can avoid the formation of a ball in the bit, eliminate the fluid area at the bottom of the well, accelerate
the upward flow of drilling cuttings and improve ROP.
2. High saturation NBR bearings can reduce sealing pressure and improve sealing reliability.
3. The G-Gauge protection improves the measuring ability and prolongs the service life of the bit.
4. Adding a row of teeth between the rear taper and the outflow to trim the borehole and protect the cone.
