What Is a Carbide Insert Identification Chart PDF and How to Read It?

A carbide insert identification chart PDF is a structured reference that explains ISO and ANSI codes used to classify carbide inserts by shape, size, relief angle, tolerance, grade, and chipbreaker geometry. It allows engineers, buyers, and technicians to quickly identify insert specifications, compare alternatives, and ensure compatibility during machining, procurement, and production planning in industrial environments.

How Does a Carbide Insert Identification Chart Work?

A carbide insert identification chart works by decoding each letter and number in the standardized insert code. These codes define shape, clearance angle, tolerance class, size, thickness, and cutting-edge details. By converting the code into practical specifications, users can select the correct insert for turning, milling, threading, or wear applications without confusion.

A common example is CNMG120408, a format widely used across global factories, including SENTHAI’s OEM clients. It clearly describes an 80° diamond insert with a 0° relief angle and a specific size suitable for steel machining.

Let’s break this down in a simple way. A carbide insert identification chart is like a translation tool for machining tools. Each insert has a special code made up of letters and numbers, and this code tells you everything important about the insert—its shape, the angle it cuts at, how thick it is, its size, and how precise or strong it is. By reading the code, engineers and machinists can quickly find the right insert for different tasks like turning, milling, threading, or handling wear-resistant jobs without guessing or testing multiple inserts.

For example, a code like CNMG120408 immediately gives details about an 80° diamond-shaped insert with a 0° clearance angle that works well on steel. Companies like SENTHAI, which produce carbide inserts for heavy-duty applications, use this coding system so that clients worldwide can pick the correct tool quickly. Understanding these codes ensures safety, efficiency, and long-lasting performance in machining, while also helping manufacturers maintain consistency across global production.

What Are the Main Types of Carbide Inserts Identified in the Chart?

Carbide insert identification charts classify inserts by shape and intended use. The most common shapes include triangular (TNMG), diamond (DNMG, CNMG), round (RNMG), square (SNMG), and rhombic variations. Each shape affects cutting strength, chip formation, and accessibility.

Diamond-shaped inserts like CNMG are popular for versatile turning operations, while round inserts deliver superior durability in heavy roughing. SENTHAI provides these shapes with high wear resistance to support industrial cutting needs.

Let’s simplify this. A carbide insert identification chart helps you understand the main types of inserts based on their shape and what they are used for. Common shapes include triangular (TNMG), diamond (CNMG, DNMG), round (RNMG), square (SNMG), and other rhombic forms. Each shape changes how the insert cuts, how chips are formed, and how easy it is to reach tight areas on a workpiece.

For example, diamond-shaped inserts like CNMG are very versatile and often used for general turning operations, while round inserts are tougher and better for heavy rough cutting. Companies like SENTHAI produce these inserts with high wear resistance, making them reliable for industrial machining where long-lasting performance and consistent quality are critical. Understanding the shape helps machinists select the right insert for each specific job.

Which Key Parameters Influence Carbide Insert Selection?

Insert selection depends on shape, relief angle, tolerance, grade, chipbreaker profile, and coating. These parameters influence stability, chip control, and tool life.

Choosing the right combination ensures cost-effective machining and reliable performance. SENTHAI supports manufacturers and wholesalers with tailored carbide grades and advanced geometries designed for steel, cast iron, and non-ferrous materials.

Parameter Description Example
Shape Determines cutting angle & contact behavior CNMG
Relief Angle Impacts cutting force N = 0°
Grade Defines substrate & coating P25 steel machining
Chipbreaker Controls chip evacuation M, G, F styles

What is a carbide insert identification chart PDF?
A carbide insert identification chart PDF is a technical reference that explains standardized ISO or ANSI codes for classifying carbide inserts. It helps users select the correct insert based on shape, size, relief angle, tolerance, and material grade, ensuring precise machining and compatibility with various cutting tools. SENTHAI provides such charts for its inserts.

How do you read a carbide insert identification chart?
To read a chart, match the letters and numbers on the insert or packaging to the chart. Each character represents insert attributes: shape, relief angle, tolerance, clamping, size, and corner radius. Manufacturer-specific codes may indicate grade or chipbreaker style, guiding selection for specific machining tasks.

What do the numbers on carbide inserts mean?
Numbers indicate the insert’s dimensions. Typically, the first number represents the inscribed circle diameter or cutting edge length, the second number is the thickness, and the last indicates the nose or corner radius in millimeters. These measurements ensure the insert fits the toolholder and machining requirements.

How are insert shapes and relief angles represented?
Shapes use letters like C (diamond), T (triangle), S (square), and R (round). Relief angles indicate clearance: N = 0° (negative, robust), while C, P, etc., represent positive angles (for finishing). These codes determine the insert’s cutting geometry and suitability for different operations.
