Roller cone drill biit IADC637 4 5/8″ (118mm)

Product Description

Wholesale API TCI tricone roller cone drill bits with discounted price in the stock from China supplier for well drilling
Bit Description:
IADC: 637 - TCI journal sealed bearing bit with gauge protection for medium hard formations with high compressive strength.
Compressive Strength:
100 - 150 MPA
14,500 - 23,000 PSI
Ground Description:
Hard,well-compacted rocks such as:hard silica limestones,quarzite streaks,pyrite ores,hematite ores,magnetite ores,chromium ores,phosphorite ores and granites.
We can offer TCI bits in avariety of sizes (from 3 3/8" to 26") and all most of IADC codes.

4 5/8" TCI tricone bit is widely used in water well drilling, exploration, HDD pilot hole, foundation piling, it has a central jet hole design, so it is also workable for reverse circulation drilling.
The bearing is sealed, the working life is much longer than open bearing roller bits. Conical shape tungsten carbide insert has higher penetrating rate than spherical shape inserts in drilling hard rocks.
