Application   Tricone bit used for geoloical prospecting,development of oil and gas,drilling water wells,blast holes and making holes for seismic prospecting,construction engineering.now there are eleven common types of tricone rock bits. Steel teeth series:IADC CODE:116,117,126,127,136,137,216,217,317,337, TCI series:IADC CODE:417,437,447,517,527,537,547,617,627,637,647,737,837. TCI tricone bit, tci roller Bits ,roller bit,steel tooth roller bit,TCI roller bit,TCI tricone bit 1.Sizes rang from 3 7/8" to 26" 2.Covers almost all IADC code. 3.Reliable quality and reasonable price   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.
