Rotating speed	150-70
formatione	Very soft formations with low compressive strength and high drillability, such as clay, mudstone, chalk, gypsum, salt rock, soft shale, soft limestone.

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 C-Center 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.
