DNMG150408 NS9530 Tungaloy turning insert — finishing, uncoated cermet for turning

DNMG150408 NS9530 Tungaloy turning insert is a rhombic ISO insert engineered for finishing operations in external and internal turning applications.

• Finishing grade NS9530 for steel
• Uncoated cermet cutting material
• Rhombic 55° geometry, 0° rake
• Double-sided chipbreaker with cylindrical hole

Superior surface quality for finishing cuts

The NS9530 grade is an uncoated cermet developed for low cutting forces and exceptionally high surface finish during finishing passes in steel. With a 0.8 mm corner radius and a sharp cutting edge, the insert reduces vibration and leaves a consistent profile when used in light depths of cut. The focused design of this finishing grade helps to achieve tight dimensional tolerances and repeatable part quality, which is essential in serial production and precision components.

Reliable ISO fit and straightforward toolholder compatibility

The insert follows ISO geometry conventions, so compatibility with a matching holder is determined by form, clearance, tolerance class, fastening and plate dimensions. The rhombic 55° geometry and 0° rake require holders designed for DNMG-style plates; correct selection ensures stable clamping and predictable chip flow. Because the fit depends on size and thickness, the 15 mm size and 4.76 mm thickness should be matched to the holder specification to guarantee secure seating and consistent tool life.

Material behaviour and machining recommendations

Manufactured from a cermet cutting material on a carbide substrate, this plate excels under continuous cutting conditions and small feed or depth settings typical of finishing operations. The double-sided chipbreaker and cylindrical hole provide reliable indexability and clamping repeatability, permitting quick rotation to a fresh edge and reducing setup time. For steel finishing, the insert performs best with modest cutting speeds and stable machine-tool-fixture combinations to exploit its sharp edge and produce superior surface integrity.

Productivity and handling advantages in daily use

Using this ISO-standard insert streamlines inventory management by offering an indexable, double-sided solution that reduces per-part tooling cost. The DNMG150408 form factor allows straightforward re-indexing and fewer tool changes, supporting continuous production runs. Combined with proper holder selection and coolant strategy, this insert contributes to reduced cycle times and improved part-to-part consistency, making it suitable for job shops and production environments focused on reliable finishing performance.

FAQ

What materials is this insert best suited for?
The DNMG150408 NS9530 insert is designed primarily for finishing in steel and performs best in continuous cutting with small depths of cut to achieve high surface quality.

How is the insert mounted and indexed?
The plate uses a cylindrical hole and is double-sided; secure clamping in a compatible DNMG holder allows simple re-indexing to a second cutting edge.

Can this insert be used for roughing operations?
This finishing-grade NS9530 insert is optimised for finishing rather than heavy roughing; for high-material-removal operations, a different grade or geometry is recommended.

What is the corner radius and why does it matter?
The corner radius is 0.8 mm, which balances edge strength with the ability to produce fine surface finishes and small profile radii in turned components.

Is this an ISO-standard insert for easy replacement?
Yes, the insert follows ISO dimensions for DNMG-style plates, enabling straightforward replacement in compatible toolholders.
