Carbide Inserts are one of the most important cutting tools used in CNC machining. They help improve machining accuracy, increase productivity, and reduce overall tooling costs by providing replaceable cutting edges instead of replacing the entire tool. Whether you are machining steel, stainless steel, cast iron, aluminium, or other engineering materials, selecting the right carbide insert can make a significant difference in machining performance.
At Metaldur, we are a trusted Carbide Inserts Supplier in India, supplying a wide range of carbide inserts for turning, milling, drilling, threading, and grooving applications. Our products are suitable for engineering industries, CNC machine shops, dealers, distributors, and bulk industrial buyers across India.
What Are Carbide Inserts?
Carbide Inserts are indexable cutting tools manufactured from tungsten carbide and designed to fit into CNC tool holders. Once a cutting edge becomes worn, the insert can be rotated or replaced, making machining more economical than using solid cutting tools.
Carbide inserts are available in various shapes, grades, coatings, ...
... and geometries to suit different machining operations. Choosing the correct insert helps improve surface finish, chip control, dimensional accuracy, and tool life.
How to Choose the Right Carbide Insert
Selecting the right carbide insert depends on several factors:
Workpiece material
Machining operation
Insert shape
Insert grade
Coating type
Cutting speed
Feed rate
Depth of cut
Machine rigidity
Required surface finish
Using the correct insert for your application helps maximize productivity and extends tool life while reducing machining costs.

Types of Carbide Inserts
Different machining operations require different insert designs. Choosing the right insert improves machining performance, increases tool life, and helps achieve better production efficiency.
1. Negative Turning Inserts
Negative Turning Inserts are commonly used for heavy-duty turning applications where strength and durability are essential.
2. Positive Turning Inserts
Positive Turning Inserts are designed with a sharper cutting edge that requires lower cutting force. They are ideal for finishing operations, thin-walled components, and materials that require smooth machining with reduced vibration.
3. Milling Inserts
Milling Inserts are widely used in CNC milling cutters for face milling, shoulder milling, slot milling, and profile milling operations.
4. Drilling Inserts
Drilling Inserts are used in indexable drilling systems to produce accurate holes with better chip evacuation and stable cutting performance.
5. Threading Inserts (MMT)
Threading Inserts (MMT) are specially designed to produce accurate internal and external threads on CNC lathes and turning centres.
6. Parting & Grooving Inserts
Parting and Grooving Inserts are designed for cutting off components and producing precise grooves in metal parts.
7. PCD Inserts
PCD (Polycrystalline Diamond) Inserts are ideal for machining non-ferrous materials and highly abrasive workpieces.
8. CBN Inserts
CBN (Cubic Boron Nitride) Inserts are specially developed for machining hardened steel, cast iron, and other hard materials.
9. Aluminium Inserts (MDAL)
Aluminium Inserts (MDAL) are specially designed for machining aluminium and other non-ferrous metals.
10. Cermet Inserts (MDC)
Cermet Inserts (MDC) combine the properties of ceramic and carbide materials to deliver excellent wear resistance and outstanding surface finish.
