By pressing or metal injection molding (MIM) followed by sintering cemented carbide powder, mainly tungsten carbide and cobalt, is formed into inserts which, compared to High Speed Steel, have a better ability to maintain their properties at higher temperatures, which enables increased cutting speed. These inserts, also called indexable inserts, are mounted on a cutting tool holder and can be repositioned to use different cutting edges before being discarded.

Centre cutting edge: Centre cutters offer high cutting edge stability with a favourable wedge angle and are particularly robust. Examples are centre cutters or bolt cutters.

Cutting edge in a parallel position:Side cutting edge: These pliers are the most widely used cutting pliers and are available in various lengths and for a wide range of materials. Examples include diagonal cutters, combination pliers, radio pliers, stork beak pliers, electricians' pliers and flat nose pliers with cutting edge.

There are six different ISO classifications of workpiece material for cutting which helps the user to choose the right cutting tool. Roughly, these can be divided into:

Cutting edges in an oblique position:Oblique cutters are specialised pliers that are used in situations where neither frontal nor lateral access to the material is possible. Although they are used less frequently than other types, they are still irreplaceable in certain scenarios.

Different cutting edge shapes play a decisive role in effectively cutting through different materials. Here are some important shapes:

Cutting edge in a perpendicular position:These pliers, such as end cutting nippers, carpenters' pincers, concreters' nippers and lever end cutting nippers, are ideal for situations where access to the material to be cut is only possible from the front or a flush cut is required. Their design enables efficient working, especially when lateral space is limited.

In addition, there are other designations that indicate the shape of the insert, release angle, tolerance class, chip breaker, holding model, size, cutting direction etc.

The cemented carbide inserts are usually coated with one or more surface layers which increase the wear resistance of the insert. The surface coats are usually applied by chemical vapor deposition (CVD) or Physical Vapor Deposition (PVD).
