8 1/2" Milled Tooth Tricone Bit &Steel Tooth Tricone Bit
TCI bits
1,Soft formations(417,437,517,537)
Features large chisel-shaped inserts to provide the highest penetration rate in the softest
formations such as shales, clays, limestone and sands.
2,Soft to medium formations(617,637)
Designed to drill effectively in formations such as hard limestone, dolomite, hard sands, and other
formations with hard cherty.
3,Medium to hard formations(737)
For extremely hard formations such as chert, granite, flint, and taconite. Features short,
closely-spaced inserts to ensure maximum penetration rate and wear resistance
Milled tooth bits
1,Soft formations(114-117)

1.How to get an exact quotation?
Answer:Please send us detailed information as below:
-Tricone bits(Diameter, IADC code)
-PDC bits(Matrix or Steel body, blades quantity, cutter size, etc)
-Hole opener(Diameter, size of pilot hole, hardness of rocks, thread connection of your drill pipe, etc.)
-Roller cutters(Diameter of cones, model number, etc.)
-Core barrel(Diameter, quantity of cutters, connection, etc.)
A simple way is sending us photos .
Besides above, if possible please provide more information as below:
Drilling depth in vertical well drilling, Drilling length in HDD, hardness of rocks, Capacity of drill rigs, application(oil/gas well drilling, or water well drilling, or HDD, or foundation).
Incoterm: FOB or CIF or CFR, by plane or ship, port of destination/discharge.
The more information provided, the more exact quotation will be offered.I am Ashion, you can contact me directly
