DNMG150404 NS9530 Tungaloy insert — ISO turning insert, 0.4 mm radius

A DNMG150404 NS9530 Tungaloy insert engineered for precision external and internal turning on steel, optimised for finishing passes and small depths of cut

• Finishing-grade uncoated cermet NS9530
• 0.4 mm nose radius for fine tolerances
• ISO DNMG150404 rhombic geometry
• Double-sided insert with cylindrical hole

High-quality finishing performance for steel turning

The DNMG150404 in the NS9530 grade is an uncoated cermet developed for finishing applications on steel. Its sharp cutting edge and low cutting forces reduce built-up edge and help achieve a high surface finish even on continuous cuts and small depths of cut. Cermet grades combine ceramic hardness with metallic toughness, which in this case supports reduced friction and improved dimensional stability during long finishing cycles. The result is fewer reworks and more consistent part quality in serial production.

Geometry and clamping for consistent productivity

The insert’s rhombic DNMG150404 geometry with a 55° included angle and 0° relief ensures predictable engagement in typical ISO holders. The 0.4 mm nose radius provides a balance between fine detail and edge strength, making the insert suitable where tight tolerances and low roughness are required. Being double-sided with a cylindrical hole, the insert offers economical indexing and secure clamping; compatibility with the chosen holder is determined by form, clearance angle, tolerance class, clamp style, size and thickness, allowing straightforward integration into established tool systems.

Process stability, efficiency and economical operation

Selected for finishing, the NS9530 grade supports stable chip formation and repeatable surface integrity on steel, which contributes to process reliability and predictable cycle times. The combination of low cutting forces and a sharp edge reduces machine load and can lower energy demand in high-volume operations. Produced to ISO standards and manufactured by Tungaloy, the insert offers consistent batch-to-batch performance and simplifies tool management for production environments that prioritise surface quality and repeatability.

FAQ

What advantages does the NS9530 grade offer over standard coated grades?
The NS9530 uncoated cermet grade provides a sharp cutting edge and reduced cutting forces, making the DNMG150404 NS9530 particularly effective for finishing steel where surface quality and dimensional accuracy are priorities.

Is this insert suitable for internal turning as well as external turning?
Yes; the DNMG150404 geometry and the insert’s compact 0.4 mm nose radius allow use in both external and internal turning applications, provided a compatible ISO holder and secure clamping are used.

How is the insert secured in the holder?
The insert is double-sided and features a cylindrical hole for positive location and clamping; correct compatibility depends on matching form, clearance angle, tolerance class, clamp arrangement, size and thickness.

For which machining conditions is this insert optimised?
The DNMG150404 NS9530 is optimised for finishing cuts on steel, continuous cutting and small depths of cut where low cutting forces and excellent surface finish are required.

Does the DNMG150404 NS9530 support economical indexing?
Yes; being double-sided allows two cutting edges per index position, which helps reduce tooling costs and downtime for index changes.
