API and ISO factory of TCI Tricone Bit IADC417 17 1/2 inches with discounted price.
Bit Description:
IADC: 417 - TCI journal sealed bearing bit with gauge protection for soft formations with low compressive strength and high drillability.
Compressive Strength:
65 - 85 MPA
9,000 - 12,000 PSI
Ground Description:
Long intervals of very soft poorly compacted shales, dolomites, sandstones, clays, salts and limestones.
Far Eastern Drilling can offer tricone drill bits in a variety of sizes (from 3” to 26”) and most of IADC Codes.
We have TCI and Steel tooth tricone bits according to cutting materials. .
We also called Steel tooth tricone bits as milled tooth tricone bit because the teeth are produced by milling machine, the cone surface is hard-faced by tungsten carbide.
Steel tooth drills are suitable for extremely soft formations with low compressive strength and high drillability .It is important to choose siutable drill bits for drilling project.Our engineer can desing the drawing to choose the best drill bits for you.
