Types of Carbide Inserts
Carbide inserts come in a large variety suited for different applications.
The common types include the following:
Turning carbide inserts
Threading carbide inserts
Grooving carbide inserts
Milling carbide inserts
Drilling carbide inserts
Boring carbide inserts

Main Considerations for Selecting Right Carbide Inserts
When choosing the correct carbide inserts, there are several parameters you must consider.
Ultimately, such factors determine whether you’ll attain good machining performance and chip control for desirable results.
Here are the main parameters to have in mind;

a)Carbide Insert Geometry
Geometries can be divided into three primary styles based on mode of operation.

These styles include
Roughing – It is high depth of cut and feed rate combinations suitable mostly for operations, which require highest edge security.
Medium – Ideal for medium operations to light roughing. Feed rate and wide range of cut depth combinations.
Finishing – Suitable for operations at light depths of cut and relatively low feed rates. Fit for operations requiring low cutting forces.

b)Carbide Insert Grade
Primarily, the insert grade is usually determined based on the following;
Component material
Method of operation (Finishing, medium, roughing)
Machining conditions, i.e., good, average, or difficult.
Technically, the tool geometry and grade complement each other.
For instance, toughness of a grade can compensate for a lack of strength in a carbide insert geometry.

c)Carbide Insert Shape
When selecting carbide shape, it is important to ensure it is a relatively required tool entering angle accessibility.
Always consider choosing the largest possible nose angle to provide insert and reliability.
However, this must be balanced against cuts variation that needs to be performed.
Ideally, a large nose angle is sturdy but requires more machine power. Also, it has a higher tendency for vibration.
On the other hand, a small nose angle is relatively weak and has small cutting edge engagement.
Therefore, it tends to be more sensitive to the varied effects of heat.

d)Carbide Insert Size
Always select a carbide insert size based on the specific application needs and space for cutting tools in the application.
Relatively large insert size provides better stability.
Heavy machining requires a carbide insert size of above IC 25mm.
When choosing the right size of carbide insert, always determine the largest depth of cut.
Consider the cutting length while determining the tool holder entering tool, depth of cut, and machine specification.

e)Material to be Machined
Carbide inserts are used for machining different types of materials.
Thus you must ensure you are choosing the right tool suitable for the specific material.
Some of these materials include the following;
Aluminum
Bronze
Hardened tool steel
Soft tool steel
Stainless steel
Cast Iron
Non-ferrous metals
Heat-resistant alloy. Titanium alloy
High hardness materials

f)Type of Machine Tool
Machine tools used with carbide inserts also come in a large variety.
The commonly used ones include the following; Swiss-type, CNC lathe, 5 axis, turning machine, lathe machine, conventional VMC among others.
