A 60° TNMG-type pressed insert is a widely used turning tool insert designed for efficient metal cutting in general machining applications. Its triangular shape with a 60-degree included angle makes it well suited for turning, facing, profiling, and light to medium roughing operations. Because of its geometry, the insert offers a practical balance between cutting strength, edge accessibility, and productivity. It is commonly chosen for CNC lathes, automatic turning machines, and conventional turning equipment where stable performance and consistent chip control are important.The TNMG-type insert is typically negative rake and double-sided, which means it provides multiple cutting edges and better economy in use. This design helps reduce tooling cost because each insert can be indexed to a new cutting edge when one edge becomes worn. The pressed manufacturing process gives the insert a strong and durable structure, making it suitable for demanding machining conditions. Compared with some ground inserts, pressed inserts are often preferred for general-purpose cutting because they combine strength, wear resistance, and cost efficiency.The 60° point angle allows the insert to enter the workpiece smoothly while maintaining good edge strength. This makes it appropriate for machining a variety of materials, including carbon steel, alloy steel, cast iron, and some stainless steels, depending on the chosen grade and coating. Different substrate materials and surface treatments can further improve wear resistance, crater resistance, and heat tolerance. As a result, the same insert style can be adapted to different machining needs by selecting the right chipbreaker and coating specification.A key advantage of the TNMG-type pressed insert is its versatility. It can be used for both roughing and finishing, although the exact cutting performance depends on the chipbreaker design and toolholding conditions. In roughing applications, it can remove material efficiently with strong cutting edges and good chip evacuation. In finishing operations, it can produce acceptable surface quality when used with proper feed, speed, and depth of cut. The insert is also valued for its stable cutting behavior, especially in operations that require repeated tool changes and dependable dimensional accuracy.Proper chip control is another important feature. Many TNMG inserts are designed with chipbreakers that help curl and break chips effectively, reducing the risk of chip entanglement and improving machining safety. This is especially useful in automated production, where continuous and predictable machining is essential. The insert’s geometry also contributes to lower cutting forces in suitable applications, which can help extend tool life and reduce machine load.Overall, the 60° TNMG-type pressed insert is a practical and economical cutting tool solution for modern machining. Its combination of strength, repeatability, multiple cutting edges, and broad application range makes it one of the most common insert styles in turning operations. For manufacturers seeking reliable performance and efficient tool usage, it remains a dependable choice across a wide variety of metalworking tasks.
