DNMG150408 NS9530 Tungaloy turning insert (finishing)

DNMG150408 NS9530 Tungaloy is an ISO-indexed turning insert engineered for fine finishing in steel machining, offering a sharp cermet grade and stable cutting performance.

• ISO rhombic DNMG profile, 55° cutting angle
• Uncoated cermet NS9530 for fine finishing
• Sharp cutting edge for low cutting forces
• Double-sided chipbreaker with cylindrical hole

High-quality finishing for steel components

The uncoated cermet NS9530 is formulated as a finishing grade, delivering a sharp cutting edge and low cutting forces that help achieve superior surface quality on steel parts. Optimised for continuous cuts and small depths of cut, this insert promotes consistent surface finish where tight tolerances and smooth finishes are required. The cermet substrate offers wear resistance at finishing speeds while maintaining the edge geometry necessary for delicate passes.

Stable geometry and reliable system compatibility

The rhombic DNMG geometry with a 55° approach provides a balanced cutting angle for external and internal turning applications. Compatibility with toolholders depends on the insert form, 0° clearance angle, tolerance class, attachment type, nominal 15 mm size and 4.76 mm thickness; correct matching ensures secure clamping and repeatable results. The double-sided chipbreaker and cylindrical hole support economical indexability and stable seating, while the 0.8 mm corner radius is suitable for producing fine edge contours without excessive burr formation.

Practical guidance for machinists and production engineers

As part of a system comprising an ISO insert, a suitable external holder or boring bar, a shim/clamping set and spare fixing screws, this insert simplifies inventory and tool-change logistics. For best results, pair the grade with stable setups and moderate feeds consistent with finishing passes; continuous cutting is preferred. Inspect seating and clamp integrity before operation and replace the insert when edge wear compromises surface quality. For machining advice or specification matching, technical enquiries are welcomed to ensure the insert fits the holder geometry and application requirements.

FAQ

Is this insert suitable for finishing operations on steel?
Yes. The DNMG150408 NS9530 Tungaloy insert is a finishing-grade cermet designed for steel machining, offering a sharp edge and low cutting forces for improved surface finish during continuous cutting.

Which turning operations are appropriate for this insert?
The insert is intended for both external and internal turning tasks; it functions as part of an ISO insert system used with compatible external holders or boring bars.

How can compatibility with a toolholder be ensured?
Compatibility is determined by the insert form, 0° clearance angle, tolerance class, attachment method, plate size (15 mm) and thickness (4.76 mm); verify holder specification matches the DNMG150408 geometry before use.

What are the key geometry and dimension details?
Key values include a 0.8 mm corner radius, rhombic DNMG form with a 55° cutting angle, 4.76 mm thickness and a cylindrical centre hole; the insert is double-sided for economical indexing.

Is the grade suitable for interrupted cuts or heavy roughing?
The NS9530 finishing grade is optimised for continuous cuts and small depths of cut; for heavy roughing or heavily interrupted cuts, a more robust grade would be preferable.
