Metal Face sealed TCI Drill Bit IADC437 8 1/2″ (215mm or 216mm) is for soft formation well drilling.
Bit Description:
IADC: 437 – 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 7/8” to 26”) and most of IADC Codes.

1>8 1/2″(215mm or 216mm) is a regular size in deep well drilling like oil and gas well drilling, and it is also a regular size in horizontal directional pilot hole drilling.
2>We have two types of tricone bit according to grades of bearing , one is Elastomer sealed bearing with normal quality and price, another is Metal-face sealed bearing with higher performance and price.
3>For very deep well drilling, we recommend Metal-face sealed bearing tricone bits in drilling depth exceeds 1000 meters, for hard rock and long distance trenchless pilot hole drilling that length exceeds 300 meters we also recommend metal-face sealed bearing tricone bits.
4>For water well drilling, shallow well drilling or shorter distance trenchless pilot hole drilling projects, elastomer(rubber) sealed bearing tricone bits has better cost performance.
