Wholesale API steel tooth sealed tricone rock drill bits in the stock based on the lowest price and excellent quality from China manufacturer
Bit Description:
IADC: 111 - Steel tooth standard open bearing bit for soft formations with low compressive strength and high drillability.
Compressive Strength:
0 - 35 MPA
0 - 5,000 PSI
Ground Description:
Very soft, unstratified, poorly compacted rocks such as poorly compacted clays and sandstones, marl limestones, salts, gypsum, and hard coals.
We can offer mill tooth and TCI tricone drill bits in a variety of sizes (from 3 7/8” to 26”) and most of IADC Codes.
According to cutting material, tirocne bit can be divided into TCI bit and Steel Tooth Bit .
Steel tooth tricone bits have another name milled tooth tricone bit since 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 such as clay, mudstone, chalk, etc. They are also suitable for medium strata with high compressive strength, such as soft shale, anhydrite, medium soft limestone, medium soft sandstone. Medium stratum with a hard interlayer.
