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).

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.
