About the tricone bit
tricone bit Cutting structure: very long widely spaced ,chisel-shaped inserts and considerable cone axis offset against center line of bit ensure very high penetration rate .To secure the bit from diameter loss, the gage protection inserts have got shorter length and greater angle of the top. Formations: long intervals of very soft poorly compacted shales ,sandstone, clays, salts and soft li mestones. Size and IADC available: 3 3/4" to 26" IADC 415,435,445,417,437,517,537,617,637,743

Cutting Structure | The durability of premium tungsten carbide insert is improved with new formulas and new techniques and new techniques. | ||
Gauge Structure | Gauge protection with gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability. | ||
Bearing Structure | Air cooling roller bearing package. Balls lock the conewhich reduces the probability of cone-dropping to minimum.The HH Tricone bit Series reduces sound to a maximum of 60 decibels at the location limit, compared to conventional rigs where sound averages up to 120 decibels. | ||
Main Type Available | Size: 8 1/2",9 1/2",9 5/8",9 7/8",10 5/8",12 1/4", etc. IADC Code:5-- Series,6-- Series,7-- Series | ||
4. Non-Sealed Roller Bearing TCI Bit | |||
Cutting Structure | Dubowitz also recommended that Washington vigorously enforce Iran sanctions, imposing heavy penalties on Tricone bit violators. His full statement is available. | ||
Bearing Structure | Non-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling; Balls lock the cone which reduces the probability of cone Cdropping to minimum. | ||
Main Type Available | The president is issuing Tricone bit edicts, Congressional representatives are falling over themselves vying for camera time to get their comments out there, and everyone is demanding answers that will not exist until a thorough drill pipe investigation by experienced oilfield professionals has been conducted. | ||

IADC tricone rollercone classification system
4 character code, first 3 characters are numbers, the last is a letter 1st number is the series. 1 to 3 represent a milled tooth tri cones, 4 – 8 represent TCI tri cones. The higher the series number the harder more abrasive the rock formation is. 2nd number is the relative degree of hardness within a series. The number ranges from 1 – 4, the higher the number the harder the formation 3rd number represents bearing design and gauge protection. 4th character is a letter and describes optional features. There are 16 alphabetic character’s each representing the tricones most significant feature.Open Bearing mill tooth tri cone roller cone bit can come with or without gauge protection
These are less expensive then sealed bearing but they typically do not last as long.
TCI Tricone bit
TCI stands for Tungsten Carbide Insert. These tri cones are designed for soft to very hard formations depending on the style and quantity of the carbides on the drill bit.
Sealed Bearing TCI Tricone bit with or without gauge protection
These are the best preforming and longest lasting style of tri cone on the market. Sealed bearings will out perform open bearings. Gauge protection greatly increases the life of the drill bit.
