Tricone IADC 537 4 1/8" single cone bits for hard rock formation Mining Mineral Drilling
Discriptions:
Roschen is a professional manufacturer of rock bits in global market, we can supply all kinds of rock bits, such as PDC bits, TCI bits, rock bits, tricone bits, single cone bits, steel tooth bits, insert tooth bits, roller bits, drill bits, drilling tools etc.
TCI bits series:
Soft Formation TCI Tricone Bits
The TCI bits are used to drill low compressive strength, very soft formations. TCI bits maximize the use of both conical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure design, combined with maximum cone offset, result in high bit penetration rates. The deep intermesh of cutter rows prevents bit bailing in sticky formations.
Adapted to be used in low compressive strength and high drillability soft rock formations (shale,clay,sands,soft limestones etc.)
These bits are used to drill low compressive strength, soft to medium soft formations. It is one of the proper bit type used in oilfields.
Drill bit design features are used to enhance bit penetration rates.
Some reduction in cone offset and insert projection is used to improve cutter durability.
Insert numbers and pitch is controlled to prevent tracking.
Size Available:
From 3 7/8"(98.4mm) to 17 1/2"(444.5mm).
Sizes and types that are not shown above can be customized according to specific drilling requirements.
TCI tricone bit / tricone rock bits:
1. Tungsten carbide insert bit of high strength and toughness is to increase the impact resistance of cutter and decrease the breakage rate.
2. Widely used in oil exploration, subterranean heat. Hydrology welling drilling and so on.
3. It is almost suitable for hard rocks, such as limestone, dolomite, chert, firm sandstone, and firm anhydrite and so on.
4. According to your request, all sorts of products can be customized.
5. Large quantities of products are in stock to meet your special need.
