DNMG150402 NS9530 — Tungaloy ISO turning insert for finishing

The DNMG150402 NS9530 is an ISO-format, rhombic cutting insert designed for precision turning and fine finishing of steel components, offering a sharp edge and low cutting forces for continuous cuts and small depths of cut.

• Finishing-grade uncoated cermet
• ISO DNMG 150402 format
• Cylindrical hole for secure clamping
• Sharp edge for low cutting forces

High-precision finishing for steel components

This insert is a dedicated finishing solution that combines the low-friction, wear-resistant properties of cermet with an optimised geometry to deliver consistent surface quality. The cutting grade is engineered for continuous cutting where repeatable finish and minimal rubbing are essential; as a result, machinists will notice reduced burr formation and improved workpiece tolerances. The use of a finishing grade also means cutting parameters can be tuned for surface integrity rather than heavy material removal, making it suitable for final passes and high-value components.

Compatibility and secure clamping for stable processes

Compatibility with toolholders depends on form, relief angle, tolerance class, fastening method, size and thickness. The insert features a cylindrical hole and standard ISO DNMG form, enabling positive seating in many external holders and boring bars. The 0.2 mm corner radius and 0° relief angle contribute to predictable engagement and minimal deflection under light cutting forces. This combination supports stable cutting conditions, reduces chatter risk and supports reproducible component quality across batches.

Efficiency gains and surface quality benefits

A sharp cutting edge with low cutting forces shortens cycle times for finishing passes by allowing higher feed rates at small depths of cut while maintaining surface finish. The uncoated NS9530 grade is optimised for steel, providing low friction and edge retention in continuous operations; this translates into fewer tool changes and more productive machine time. Process engineers can therefore balance feed and speed to achieve the desired Ra values without excessive tool wear, improving overall cost-efficiency in serial production.

When to select this grade for your turning tasks

Choose this ISO-format insert for external and internal turning where fine surface finish and dimensional accuracy are priorities. The double-sided chipbreaker and the 4.76 mm plate thickness provide economical, reversible use while the rhombic shape and 55° included angle give access in constrained geometries. This insert is particularly suitable for small depths of cut and finishing passes on steel parts where a consistent, sharp cutting edge is required rather than aggressive material removal.

FAQ

What machining tasks is this insert best suited for?
This insert is intended for finishing and fine turning of steel components; the DNMG150402 NS9530 grade offers a sharp edge and low cutting forces suitable for continuous cuts and small depths of cut.

Is the insert reversible and economical to use?
Yes, the rhombic, double-sided design allows indexable use; the plate thickness and double-sided chipbreaker support economical turning operations.

Which toolholders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and size; the cylindrical hole and ISO DNMG form allow use with standard external holders and boring bars designed for DNMG inserts.

Does the insert have a coating?
No, this is an uncoated cermet grade (NS9530), optimised for finishing applications on steel.

How does the 0.2 mm corner radius affect performance?
A 0.2 mm radius supports fine surface finishes and lower cutting forces, making it ideal for final passes where dimensional accuracy and surface quality are important.
