Wholesale API rotary steel tooth tricone drilling bit in stock based on the lowest price and excellent quality from China factory Bit Description: IADC: 217 - Steel tooth sealed roller bearing bit with gauge protection for medium to medium hard formations with high compressive strength. 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. Far Eastern Drilling can offer mill tooth and TCI tricone drill bits in a variety of sizes (from 3 ” to 26”) and most of IADC Codes.
According to cutting material,three cones 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.The steel tooth tricone bits has longer teeth than TCI tricone bits so that it can drill soft formations at high ROP.

Sealed Roller Bearings have some of the features of the non-sealed open bearings, but longer lifetime because the bearings are sealed with an O' Ring Seal. A lubrication and compensator system prevents leakage into the bearing system and stops the possibility of debris blocking the bearing as well as leakage of grease. 5 7/8" mill tooth tricone drill bit is widely used in water well drilling, oil well drilling, geothermal well drilling, it can be used for drilling cement plug in very deep well.The mill tooth tricone drill bit has longer teeth which could get much faster drilling down speed than TCI drill bits.
