Application   Tricone bits, which some may also call roller cone bits or tri-cone bits, The roller cone bit is the most widely used tool in petroleum drilling and geological drilling. Tricone bit has the function of impacting, crushing and shearing rock in formation, so it can adapt to soft, medium and hard formation. The cone bit can be divided into milling (steel teeth) cone bit and TCI cone bit according to the type of teeth. Characteristics 1. High temperature heat treatment forged . 2. Carbide teeth with high strength and toughness work more efficiently. 3. Tooth palm lip hard welding surface with hard alloy ,Effectively prevent the drill bit wear and tear work. 4. Head OD protection to effectively reduce head wear in abrasive formation and extend bit work. 5.Directional jet enlarges lateral flow area and helpful bottom hole cleaning and increase of ROP. 6. Lubricating system protection of bearing and seal system of bit extend bit work life. 7. API REG Connection. 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.
