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.
