Albany, NY -- (SBWIRE) -- 05/30/2018 -- Inserts are large-sized pieces of abrasive materials obtained by sintering a precursor powder into a consolidated mass. They are available in various shapes such as disks, rhombus, and triangles. The shape of the insert required in a tool is determined by the type of application. Commonly used cutting tool inserts are manufactured from ceramics (such as ceramic aluminum oxide and ceramic iron oxide) and carbides (such as silicon carbide (carborundum) and boron carbide).
Read Report Overview @
Carbide inserts, also known as cemented carbides, are composite materials. They are exceptionally hard materials employed in various industrial applications. For instance, they are used as cutting tool materials. Carbide inserts are manufactured as composites of carbide compounds cemented by a binder metal. Carbides that are commonly utilized in the manufacture of inserts include silicon carbide, boron carbide, and tungsten carbide. Sometimes, titanium carbide and tantalum carbide are also used as aggregates in carbide inserts.
Carbide inserts undergo coating in order to increase the life of carbide tools. Commonly used coatings are titanium nitride (TiN), titanium carbide (TiC), titanium carbide-nitride (Ti(C)N), and titanium aluminum nitride (TiAlN). Typically, lubricity and/or hardness of the tool increases when coatings are applied. Coating enables the clean pass of the cutting edge of a tool through the material. Temperature accompanying the cutting process also decreases due to coatings. This increases the tools' life.
Deposition of coatings is typically carried out with the help of the thermal chemical vapor deposition (CVD) method. Certain applications require deposition of coatings with the mechanical physical vapor deposition (PVD) method. Deposition of coatings is an intricate process; complications in the process can result in adhesion failure of the coating.
Carbide inserts and other tools are able to withstand higher temperatures vis-à-vis standard high-speed steel tools at the point of contact between the cutter and work-piece. This enables carbide inserts to perform better surface finish of the work-piece and faster machining process.
In comparison, other typical materials employed in the manufacture of machining tools (including inserts) are cheaper than carbide. Furthermore, carbide is more brittle. This increases its susceptibility for chipping and breaking. In order to avoid this, the cutting tip is formed in the shape of a small insert, which is mounted on the tool body made from another material (such as carbon tool steel). This also provides the benefit of using carbide at the cutting interface without the high cost and brittleness of making the entire tool out of carbide.
In terms of material, the carbide inserts market can be segmented into silicon carbide, boron carbide, tungsten carbide, and others. Based on application, the market can be divided into grinding, cutting, polishing, milling, drilling, and others.

In terms of geography, the carbide inserts market can be segregated into North America, Europe, Asia Pacific, Latin America, and Middle East & Africa. Asia Pacific is the hub for a large number of manufacturers of carbide inserts. In terms of consumption as well as growth potential, Asia Pacific dominated the global carbide inserts market. The region is expected to continue its dominance in the near future. This can be ascribed to the technological advancements in automotive, medical, and aerospace industries in developing countries in Asia Pacific. Latin America and Middle East & Africa are likely to account for comparatively minor shares of the global carbide inserts market due to the lack of manufacturing facilities and their export-oriented economies. Europe is estimated to experience higher consumption of carbide inserts than North America.
