Tricone bits from China factory is for hard formation oil well drilling. Bit Description: IADC: 517 - 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. Far Eastern Drilling can offer tricone drill bits in a variety of sizes (from 3 7/8” to 26”) and most of IADC Codes.
11 5/8"(295mm) API TCI Tricone Bits for Hard Rock Drilling We only specialize in rock drilling, especially in hard rock drilling, breaking the hard rocks by pressure and rotating tungsten carbide inserts tricone bits at high efficiency. Drillers always consider below factors: Working life of rock bits. Penetration rate of rock bits. Cost of drilling per meter/feet What you care about is what we care about, we provide products according to detailed drilling conditions.
