Tungsten carbide fixed kits mainly used for small batches. Under production conditions with simple step drill hole. Fixed kits is mounted directly in the corresponding holes drilled in the template, so after a fixed kits wear generally can not be replaced.

Shoulder primarily for drilling template is thin, necessary for holding the drill guide sleeve length. With the shoulder, you can prevent the cutting and coolant falls on drilling template kits hole. The lower end of fixed drilling sleeve should extend beyond drilling template, in order to prevent the ribbon cutting and increased involvement of the kits kits wear.

Tungsten Carbide Products

Tungsten carbide is a material used for a number of industrial applications and it is characterised by its high strength, toughness and hardness. Its name derives from the Swedish for tung (heavy) and sten (stone) and it is mainly used in the form of cemented tungsten carbides. Cemented carbides (also known as hardmetals) are made by 'cementing' grains of tungsten carbide into a binder matrix of cobalt or/and nickel.

Tungsten carbide as a material can vary in carbide grain size (0.2 – 50 microns) and by binder contents (up to 30%), as well as by the addition of other carbides. By varying the grain size of the tungsten carbide and the binder content in the matrix, engineers have access to a class of materials whose properties can be tailored to a variety of engineering applications. This includes high-tech tools, wear parts and tools for the construction, mining and oil and gas sector.

Tungsten carbide products typically have a high resistance to wear and can be used at high temperatures, allowing tungsten carbide's combined hardness and toughness to significantly outperform its steel product equivalents.

What is Tungsten Carbide Indexable Inserts

Tungsten carbide inserts are replaceable and usually indexable bits of cemented carbide used in machining steels, cast iron, high temperature alloys, and nonferrous materials. Tungsten carbide indexable inserts allow faster machining and leave better finishes on metal parts. Tungsten carbide indexable inserts can withstand higher temperatures than high speed steel tools.

Tungsten carbide indexable inserts are composed of a metal matrix composite where carbide particles act as the aggregate and a metallic binder serves as the matrix. The process of combining the carbide particles with the binder is referred to as sintering. During this process, the binder eventually will be entering the liquid stage and carbide grains remain in the solid stage. The binder is embedding/cementing the carbide grains and thereby creates the metal matrix composite with its distinct material properties. The naturally ductile metal binder serves to offset the characteristic brittle behavior of the carbide ceramic, thus raising its toughness and durability. Such parameters of carbide can be changed significantly within the carbide manufacturer's sphere of influence, primarily determined by grain size, cobalt content, dotation, and carbon content.

Our products provide optimum performance for a broad range of operations, including contouring, facing, slotting, and ramping. Inserts feature a unique and highly developed combination of substrate and coating configurations that can handle any workpiece material in any machining environment.

Tungsten Carbide Inserts

Tungsten carbide inserts is made from tungsten carbide powder and other binders, thanks to high precision and high reliability, tungsten carbide inserts have been widely used worldwide for improving productivity.

Tungsten carbide is more expensive per unit than other typical tool materials, and it is more brittle, making it susceptible to chipping and breaking. To offset these problems, the carbide cutting tip itself is often in the form of a small insert for a larger tipped tool whose shank is made of another material, usually carbon tool steel. This gives the benefit of using carbide at the cutting interface without the high cost and brittleness of making the entire tool out of carbide. Most modern face mills use carbide inserts, as well as many lathe tools and endmills. In recent decades, though, solid-carbide endmills have also become more commonly used, wherever the application's characteristics make the pros outweigh the cons.

Mining and tunneling cutting tools are most often fitted with cemented carbide tips, the so-called "Button Bits". Only man-made diamond can replace the cemented carbide buttons when conditions are ideal, but as rock drilling is a tough job the cemented carbide button bits remain the most used type throughout the world.

Tungsten Carbide Ball

Tungsten carbide balls are used where extreme hardness and wear resistance is required; in such applications as bearings, ball screws, valves and flow meters. These balls are also used for coining and as pivots, detents and tips for gauges and tracers. Tungsten carbide itself is practically inert and extremely strong. 

The smallest size of tungsten carbide ball we are able to provide is 2mm.Since other material is less expensive, the selection of tungsten carbide solely for corrosion resistance is usually not justified. In highly corrosive conditions, carbides with a more resistant binder can be supplied. 

Tungsten carbide balls are used in applications requiring extreme hardness and resistance to wear and abrasion; and are able to withstand hard shocks and impacts. Our tungsten carbide balls are usually made with 6% cobalt binder or 8% cobalt binder. Common applications for tungsten carbide balls include ball valves, flow meters, ball bearings, linear bearings, and ball screws. Tungsten carbide balls can also be used for coining and minting; as pivots, detents, and points or tips for gauges, tracers and comparators; and as metal balls for ballizing, hole sizing, gauging, and checking.

Tungsten Carbide Button Application

Tungsten carbide buttons are widely applied in geological prospecting, coal mining and oil well boring. Because of its wear resistance and hardness (9.8 Moe's scale), tungsten carbide is ideally suited for wear parts, other machine parts and dies which are subject to severe service conditions, such as high temperatures, corrosion and abrasion. In recent years, tungsten carbide has emerged as a superior alternative to steel in many industrial applications.

Most of this tungsten carbide wear parts and the mining tools are made of straight WC-Co hard metals without any addition of other carbides. Fine and ultrafine grained WC hard metals have become more and more important today in the field of wear parts, tools for chipless forming and cutting tools for cast iron, non ferrous alloys and wood.

Tungsten carbide button is widely used as the most popular mining bits tool in modern industries, therefore, they are also named tungsten carbide mining bits, tungsten carbide button bits or just tungsten carbide mining buttons, etc. And as their material is cemented carbide, so cemented carbide buttons are also widely used among the users.

As its unique working performance, tungsten carbide buttons are widely applied to oil filed drilling and snow removal, snow plough machines or equipments.

Cemented carbide buttons are used in the coal cutter drilling tools, mine machinery tools and road maintenance tools for snow clearing and road cleaning. Carbide mining button bits are widely applied for rock tools, mining tools for use in quarrying, mining, tunneling, and civil constructions.

Tungsten carbide hammer owns the properties of a narrow range of concentrations of mixtures of carbon and iron that make steel, a number of different metallurgical structures, with very different properties can form. Understanding such properties is essential to making quality steel. At room temperature, the most stable form of pure iron is the body-centered cubic (BCC) structure called ferrite or α-iron. It is a fairly soft metal that can dissolve only a small concentration of carbon, no more than 0.005% at 0 °C (32 °F) and 0.021 wt% at 723 °C (1,333 °F). At 910 °C pure iron transforms into a face-centered cubic (FCC) structure, called austenite or γ-iron. The FCC structure of austenite can dissolve considerably more carbon, as much as 2.1% (38 times that of ferrite) carbon at 1,148 °C (2,098 °F), which reflects the upper carbon content of steel, beyond which is cast iron.

Tungsten carbide drawing dies cores during sintering shrinkage will produce different batches because ingredients, pressing and sintering processes are different, there are large differences in the amount of shrinkage; die blanks all parts vary the amount of shrinkage, often form a "saddle" or "bell" shape. Dimensions fluctuations die blanks, although in line with standard die blanks, but far more than the mold inserts suit the requirements of interference caused when loading inserts core prestressed bear serious inequality, mold life greatly reduced, and therefore, must die blanks were cylindrical grinding, grinding machine using a special need in the fixtures, diamond grinding wheel.

What is Tungsten Carbide Blank

Tungsten carbide blank is a kind of solid tungsten carbide. They are made of grains of tungsten and carbon held together in a matrix of metal such as cobalt or nickel. There are many different grades of tungsten carbide. Refer to our carbide and advanced material section for more articles on carbide.

Tungsten carbide blank material can be called a powdered metal because tungsten is a metal. It is also classified as a ceramic. Ceramics are often defined as a class of materials that are not anything else. It can actually make the most sense to think of tungsten carbide as a ceramic when you are using it and a powdered metal when you make it.

Tungsten and most metals arrange themselves in a lattice which is like a 3 D version of a chain link fence. Under great heat and pressure the carbon atoms are actually packed inside the tungsten atoms instead of being joined side by side as with ordinary compounds.

Tungsten carbide blanks are very common material on any sort of cutting tool: For example, saw blades, lathe bits, drill bits, router bits and dental drilling tips are generally made of carbide. Carbide is so popular in these sorts of tools because it stays sharper longer than most other materials. Additionally, some ball-point pens use carbide balls because it helps the pen last longer.

With something like a carbide blanks, the main body of the blade is made of steel. The small tips of carbide are brazed on to the body. A good carbide tip might hold an edge ten to twenty times longer than a tool steel tip.

Tungsten carbide turning tool have 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 workpieces 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 wear is less when cutting the sintered tungsten carbide containing larger amount of cobalt binder. The surface roughness of about 2μm in Rz is obtained.
