CNMG 090404 NS9530 – CNMG turning insert for finishing, Tungaloy

CNMG090404 NS9530 Tungaloy turning insert provides a finishing-grade solution for continuous cuts and fine surface requirements in turning operations.

• ISO CNMG geometry, size 09
• Uncoated cermet grade NS9530
• 0° clearance for fine finishing
• Double-sided chipbreaker, cylindrical hole

High-precision finishing with low cutting forces

The NS9530 grade is an uncoated cermet developed for finishing in steel, offering a sharp cutting edge and low cutting forces. This combination reduces built-up edge and supports consistent part quality when cutting with small depths of cut or in continuous feed conditions. The result is a reliable route to improved surface finish and reduced secondary operations. Because the grade is optimised for low forces, tool life is often extended in stable setups, making it suitable for precision shops and serial finishing tasks.

Easy integration into ISO systems and secure clamping

Designed to the ISO CNMG standard, the insert fits established holders when form, clearance, tolerance class, fastening type, size and thickness match. The CNMG090404 shape and the standardised geometry simplify tool selection and inventory management across CNC lathes. The insert’s compatibility is determined by measurable attributes—such as thickness and hole style—so retrofitting into an existing tool system is straightforward when the matching holder is chosen. This reduces downtime and accelerates changeover for production runs.

Stable chip control and repeatable indexability

Equipped with a double-sided chipbreaker and a cylindrical hole, the insert provides consistent chip formation and secure fastening in the seat. The double-sided design allows two cutting edges per index, improving economy per insert and enabling quick edge changes without complex regrinding. In combination with the insert’s geometry, the chipbreaker supports smooth evacuation under continuous cutting, which helps to avoid chatter and maintain dimensional stability on turned components.

Recommended use and suitable applications

As a finishing grade, the insert is particularly effective for external and internal turning where surface integrity is critical and feed rates are moderate. The insert suits operations on steel where a sharp edge and minimal plastic deformation are required. For best outcomes, select the chipbreaker and grade to match material, cutting conditions and machine stability; stable fixturing and consistent coolant application further enhance performance.
