Product Description

Wholesale API Tungsten Carbide Insert rock roller drillling bits in the stock from China factory
Bit Description:
IADC: 537 – TCI journal sealed bearing bit with gauge protection for soft to medium soft formations with low compressive strength .
Compressive Strength:
85 – 100 MPA
12,000 – 14,500 PSI
Ground Description:
Medium hard and abrasive rocks such as sandstones with streaks of quartz, hard limestone or chert, hematite ores, hard, well-compacted abrasive rock such as: sandstones with quartz binder, dolomites, quartzite shales, magma and metamorphic coarse grained rocks.
We can offer TCI bits in avariety of sizes (from 3″ to 26″) and all most of IADC codes.
According to cutting material,tirocne bit can be divided into TCI bit and Steel Tooth Bit .
TCI is short for Tungsten Carbide Insert, tungsten carbide is regular hard material in rock drilling field, another material is diamond.
Inserts means Tungsten Carbide teeth that’s fitting on cones of rotary drilling roller cone bits. .API TCI tricone bit. IADC537 8 1/2″ (215mm/216mm) have type of Rubber /Elastomer sealed bearing and Metal sealed bearing. We suggest that we had better choose metal face sealed bearing bits for deep rock wells with hard formations.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.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.
