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 Oring, 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. 6.Advantage: 1. High-strength, high flexibility, high temperature and high wear resistance. 2. High-precision metal seal. 3. Locking roller ball, to adapt to high-speed. 4. The use of high strength high toughness carbide teeth, 5. Hours in the rotary cone bit with the impact, crushing and shearing the role of broken rock. 6. Cone bit to adapt to the soft, medium and hard of various strata. 7. Reasonable price and long working life.

Die Grinder Bits Carbide Tooling Tungsten carbide burrs 1. The Description of Tungsten Carbide Burr: Carbide rotary burr is used with high-speed electric grinders orpneumatic tools, which are widely used in industrial sectors such asmachinery,automobiles, ships, chemicals, and crafts. Carbide rotary burr can be used to processmachine cast iron, cast steel, carbon steel, alloy steel, stainless steel,hardened steel, copper and aluminum. 2. The Feature of tungsten rotary carbide burr: Great efficiency, high degree of finish, long service life and high accuracy. Easy to use, safe, reliable, economical and labor-saving. Work with high-speed electric grinders or pneumatic tools.. Can process all kinds of metal(such as iron, steel,copper,aluminum) and non-metal (such as marble, jade, bone). Widely used in machinery,automobile,ships,chemical,craft and more. 3.The recommended application of various types of tungsten carbide burr: Arch ball/pointed nose engraving, texturing, increasing hole size Ball concave cuts, hollowing, shaping, carving. Useful for wood, stone, metal engraving. Ball nose cone rounding edges, surface finishing, tight spaces, and angles. carbide ball nose cylinder- contour finishing Ball nose tree (also known as tapered) concave cuts and rounding edges Cone rounding edges, surface finishing, tight spaces, hard to reach areas. Cylindrical contour finishing and right-angled corners Cylindrical end cut contour finishing Carbide Cylindrical no end cut contour finishing Flame channel work and shaping Inverted cone v-cuts and rear-side chamfering Oval die grinding and engraving Pointed tree concave cuts, rounding edges, access to hard-to-reach areas, and acute angles. Rounded tree concave cuts and rounding edges 4.Service supplied: Full types for choice OEM&ODM Competitve price,stable quality,short lead time Solid carbide burr,long shank carbide burr,carbide burr set supplied Can engrave as requirement Package:extension tube for one pieces(the color could be blue,yellow) 5.The details of three different types of cut shape of carbide burr: Single cut burrs are primarily for general purpose fluting,milling,and cleaning,which produce long chips,and are ideal for heavy removal of material. Double cut burrs creat small chips and a good finish,which are efficient at stock removal in harder materials.The additional flute reduce pull and increase operator control.Best for medium to light removal of material.It can be used at slower than normal speeds. Coarse cut burrs(aluminum cut burr) remove stock quickly,and provide large flute area in softer ferrous and non-ferrous and non-ferrous materials.

Tungsten carbide gripper jaws tips are tools used to clamp and hang the casing string during the drilling process. They are used to clamp or place between the casing of the drill pipe. They are used to tighten and hang the casing string and oil string in the well to prevent them from falling into the well. Note: Other specification can be made upon customer's requirements.

Zhuzhou tongda has in tungsten carbide turning tool possession an advanced production line for manufacturing dies and moulds and a production line for post machined cemented carbide products. We can also supply tailor-made products of various specifications based on the requirements of our customers. Because of tungsten carbide turning tool high precision and high reliability, tungsten carbide inserts have been broadly used worldwide for significant productivity improvements. Tungsten carbide has extremely high hardness and wear-resistivity compared with conventional steel materials, and it is expected that the tungsten carbide can be applied widely to dies and molds in the near future. In order to develop an efficient machining method of tungsten carbide for the dies and molds, series of cutting experiments were carried out to turn the sintered tungsten carbide materials with CBN tool. The selected sintered tungsten carbide work pieces are those containing tungsten carbide grains with mean grain size of 5µm, and 15wt%, 20wt% and 22wt% of cobalt binder. The sintered CBN tool selected contains super-fine grains of CBN with mean grain size of 1µm. The cutting speed was varied from 10m/min to 60m/min, and the tool wear and the surface roughness were measured. It is concluded that the tool wears less when cutting the sintered tungsten carbide containing larger amount of cobalt binder. The surface roughness of about 2µm in Rz is obtained. Tungsten Carbide Turning Tool Feature 1. Long life 2. Good toughness and hardness 3. High precision 4. Working efficiency 5. Right hand and left hand available 6. Accessories with pretty good quality The notable and rare combination of physical properties possessed by tungsten carbide makes it useful for a variety of applications. It is extremely strong and wear-resistant. There are only a few materials on earth that can be used to cut or engrave tungsten carbide, with industrial diamond abrasives being one of these. Its tensile strength is very high, but it is brittle under high pressures as a result. The melting point of tungsten carbide is also very high, at 5,200 degrees Fahrenheit.
