Tricone bits introduction 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. Tricone bits Structure Guidance of Tricone Bit Choice

IADC	WOB(KN/mm)	RPM(r/min)	APPLICABLE FORMATIONS
114/116/117	0.3~0.75	180~60	Very soft formations with low compressive strength and high drillability, such as clay, mudstone, chalk, etc.
124/126/127	0.3~0.85	180~60	Soft formations with low compressive strength and high drillability, such as mudstone, gypsum, salt, soft limestone, etc.
134/135/136/137	0.3~0.95	150~60	Soft to medium formations with low compressive strength and high drillability, such as medium soft shale, hard gypsum, medium soft limestone, medium soft sandstone, soft formation with harder interbed, etc.
214/215/216/217	0.35~0.95	150~60	Medium formations with high compress strength, such as medium soft shale, hard gypsum , medium soft limestone, medium soft sandstone, soft formation with harder interbed, etc.
227	0.35~0.95	150~50	Medium hard formations with high compressive strength, such as abrasive shale, limestone, sandstone, dolomite, hard gypsum, marble,etc
Note: The upper limits of WOB and RPM in above table should not be used simultaneously.
