Types of Carbide Inserts: Shapes, Grades & Coatings Guide

What Are Carbide Inserts?

Carbide inserts are indispensable high-performance cutting tools in modern metalworking and machinery manufacturing. They are typically made of a combination of tungsten carbide (WC) and cobalt (Co), possessing extremely high hardness and wear resistance. They can maintain the stability of the tool tip under high-speed and heavy-load cutting conditions, and are not easily deformed or chipped.

Compared to traditional high-speed steel (HSS) cutting tools, carbide inserts not only offer higher cutting efficiency but also have a longer lifespan, significantly reducing production costs and tool replacement frequency.

They are widely used in industrial applications such as CNC turning, milling, drilling, and mold processing, and are suitable for a variety of materials including steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys.

Carbide Insert Types

The classification of carbide inserts can be conducted based on multiple dimensions such as shape, cutting method, material grade, and coating. Understanding these types is essential for selecting the correct tool for your machining needs.
