Our tricone bits can be devided into two series: steel tooth tricone bit (mill tooth tricone bit) and TCI tricone bit (tungsten carbide tricone bit), both of which are used for mining, piling, water well drilling and oil well drilling. Our tri-cone bits are of American style and we process our products strictly according to API standard and ISO9001-2001 quality controlling certificate, that can ensure you of our offering good quality products. Product Specification/Models: various sizes and styles Steel tooth tricone bit: IADC 127, 126, 117, 216, 125, 215, 311 TCI tricone bit: IADC 517, 527, 537, 547, 617, 515, 525 Application: for water well drilling, oil well drilling, mining, piling. Packed by case.

Tricone Bits are designed for multiple drilling applications, such as Gas and Oil production, Mining and Mineral Exploration, Water Well production, and various other industrial uses. Tricone bits we supplied are made from high quality materials (steel forging, carbide, and others) as per API spec 7 or ISO9001 system, including S series elastomer sealed journal bearing bit, S series non-sealed journal bearing bit, SV series six-point position stabilization motor bit, SL series pilot hole-reaming core bit, SD series single cone bit, etc. Please provide IADC code when asking for quotation.

TRICONE BITS : tricone drill bit is used when working with soft rock formations. Tricone drill bits that are ideal for soft rock formations will have long protruding teeth. They are also used to drill medium rock formations which include dolomites, hard limestone, and calcites. Core Bits APPLICATIONS:- ->Glass ->Ceramics ->Tile ->Rock and stone ->Granite and marble ->Concrete ->Masonry products ->Hard metals

The products of our company have achieved industrialization and serialization.Besides our company has always laying importance on the technical exchanges and cooperation with the counterparts both at home and abroad.Our products have been sold all over the world, including the United States, England,Canada,Brazil,Russia,Italy,Iran,Saudi Arabia,Korea, India, and Poland and so on. The main products we can provide: 1.tricone bit(steel tooth and tungsten carbide insert tooth bit) 2.PDC bit(steel body and matrix body PDC bit) 3.rock hole opener for vertical and horizontal directional drilling, rock reamer 4.other drilling tools(single tricone cutter, mud motor, drill rod, drag bit, etc)

1.Cutting structure this type TCI tricone bits: The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit. 2.Gauge structure this type TCI tricone bits: Multiple gauge protection with gauge trimmers on the heel of cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life. 3.Bearing structure of this type TCI tricone bits: High precision bearing with two thrust faces. Ball lock the cone. Hardfaced head bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved. 4.Seal and Lubrication of this type TCI tricone bits: Premium O-ring, optimal seal compression and curved seal structure can enhance the seal performance. The pressure compensator system and advanced grease can greatly increase the lubricating reliability . 5.Product Application this type TCI tricone bits: It can receive high WOB in the conventional drilling. It is suitable for various formations by matching cutting structure with different tooth shape, tooth density and tooth exposure height.

Product Description: Steel teeth Bits 114-117, 127 Soft Formation Tooth Bits The 114-117 bits are used to drill low-compressive strength, soft formation. Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistant hard facing is used to control tooth wear. On the softest bits type this hard facing completely covers the bit teeth. 127 Medium-Hard Formation Tooth Bits The 127 bits are used to drill high-compressive strength, medium hard formations. Short projection teeth with reduced crest length are used in this series of bit designs. Durable hard facing is applied to reduce tooth wear. Medium hard with high compressive strength and hard streak (hard shale ,sandstone , limestone, etc.) 437 Soft Formation TCI Tricone Bits The 437 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. 517 Medium Formation TCI Tricone Bits The 517 features aggressive chisel tungsten carbide insert on the heel rows and inter rows. This design provides a fast drilling rate and added cutting structure durability in medium-to-medium hard for-mationes. The HSN rubber O-ring provides adequate sealing for bearing durability. 637 Hard Formation TCI Tricone Bits The 637 bits can be used to drill hard and abrasive forma-tions. Wear-resistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge. Maximum numbers of hemispherical-durability and long life. 617 Medium-Hard Formation TCI Tricone Bits The 617 feature robust chisel tungsten carbide inserts on the heel row and conical on the inner rows. This design provides a fest drilling rate and added cutting structure durability in medium to medium hard formations. The HSN rubber O-rin provides adequate sealing for bearing durability. Plywood case or according to the conform order.
