Hot sale API TCI tricone bit for well drilling for deep oil well with 5% discounted price in stock Bit Description: IADC: 617 - TCI journal sealed bearing bit with gauge protection for medium hard formations with high compressive strength . The advantages of using Tri cone over other drill bits 1)There is a Tri Cone suitable for any rock formation 2)Tricone bit is versatitle and can handle changing formations. 3)Tri Cone are resonalbly price,long lasting and have an efficient drilling rate. 4)Tricone is that the roller cones have high end sealed bearings,extremely high quality tungsten carbide and diamond gauge protection throughout the drill bit as well as skirt tail hard facing and optimized hydraulics.
1. 6"(152.4mm) is a regular size in deep well drilling like oil and gas well drilling, and it is also a regular size in horizontal directional pilot hole drilling. 2.We have two types of tricone bit according to grades of bearing , one is Elastomer sealed bearing with normal quality and price, another is Metal-face sealed bearing with higher performance and price. 3.For very deep well drilling, we recommend Metal-face sealed bearing tricone bits in drilling depth exceeds 1000 meters, for hard rock and long distance trenchless pilot hole drilling that length exceeds 300 meters we also recommend metal-face sealed bearing tricone bits. 4.For water well drilling, shallow well drilling or shorter distance trenchless pilot hole drilling projects, elastomer(rubber) sealed bearing tricone bits has better cost performance.| Basical Specification | |
