Tricone bits manufacturers IADC117 6 3/4 inches (171mm)

Product Description

Wholesale API steel tooth sealed tricone drill bits in the stock based on the lowest price and excellent quality from China supplier

Bit Description:
IADC: 117 - Steel tooth journal sealed  bearing bit with gauge protection 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 tricone drill bits and TCI tricone bits in a variety of sizes (from 3” 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 (or Mill Tooth) bits come in many shapes and sizes with multiple features, and cutting structures to combat downhole diversities in the different form ations you may encounter. Milled tooth tricone bits are designed for very soft to medium hardness formations.
Far Eastern Drilling offer top-of-the lFAR EAine tricone drill bits.
We promises the highest performance, reliability, and availability. This effectively results in a lower drilling cost.

Formation

Very soft formations with low compressive strength and high drillability,such as clay,mudstone,chalk,etc.

7 1/2 inches is a regular size in water well drilling, it is working well with small capacity drilling rigs and widely used in the world.
Steel tooth tricone rock bit is also named milled tooth tricone rock bit could drill soft mudstone, even soft limestone, the cones are hard faced by tungsten carbide, the bearing is journal and locked by ball, high grade elastomer(rubber)-HNBR O-ring sealed bearing, grease compensating system lubricate the bearing , the working life is very long.
