Far Eastern Drilling are API (API-7-1 & API Spec Q1) factory specializes in drill bits, such as Tricone Bit,PDC Bit,Hybrid Bit,HDD Hole Opener,Foundation Roller Cone Bits and related drilling tools,application fields includes for oil well drilling, gas well drilling, geothermal well drilling, mining, geological survey, hydrographic survey, water well drilling, HDD pipelines installation projects, foundation rock piling projects. We can offer both TCI and Steel (Milled) Tooth in a variety of sizes and all most of IADC codes in stock.
Hole opener / Hole rock reamers can be divided into milled tooth cone reamer and TCI cone reamer. A hole opener is a device used to enlarge the borehole druing a well drilling operation.It can be positioned either above the drill bit or above a pilot run inside the existing borehole. Usage range from hydrocarbon drilling operations to water drilling or horizontal drilling.
In hard and long rock crossing, working life of rock reamer is extremely important , one-time cross successfully saves huge cost of labor, cost of renting rigs, cost of drilling consumables. If one-time cross failed, it would be huge cost for drillers to pull out the reamers and reaming again.
Metal-face sealed bearing roller cone has perfect performance in drilling long and hard rock sections, drillers don't need to worry when using metal-face sealed bearing roller cones.
The horizontal directional drill reamer could work with trencher of Ditch Witch, Vermeer, etc , the
thread connection could be produced to NC, FH, IF, REG, FS, ... to be connected with various of drill pipes.
Main parameter of drill reamer, all below parameters could be customized:
1>Shaft OD and length;
2>Thread connection;
3>Diameter of reamer;
4>Diameter of stabilizer;
5>Type&Qty of roller cone cutters.
