TNGG220408 NS9530 ISO turning insert for turning (Tungaloy)

The TNGG220408 NS9530 is an ISO-standard triangular indexable insert designed for precision turning and finishing of steel components, with a sharp cutting edge and a low-relief geometry for continuous cuts.

• ISO triangular insert TNGG form
• Uncoated cermet finishing grade NS9530
• 0.8 mm corner radius for fine finishes
• Cylindrical hole, double-sided for cost efficiency

Consistent finishing performance through a dedicated cermet grade

This finishing insert uses an uncoated cermet grade engineered as NS9530, offering a sharp cutting edge and low cutting forces that favour continuous turning operations. The microstructure of cermet provides a stable edge and reduced built-up edge formation when machining steels, which directly translates to improved surface quality and fewer rework cycles. For customers requiring a predictable finish on small depths of cut, this grade ensures reliable results while maintaining tool life and process stability.

Geometry and build that support repeatable production

The triangular 60° geometry combined with a 0.8 mm corner radius delivers a balance between strength and fine finishing capability. The insert is double-sided, extending service life by enabling indexing, and is supplied with a cylindrical hole for secure clamping in compatible holders. As an ISO-standard insert, compatibility with matched holders is governed by form, relief angle, tolerance class, fastening method, size and thickness, so integration into existing tool systems is straightforward and predictable. Clear geometry also aids in consistent chip flow and vibration control.

Shop-floor benefits: efficiency, predictability and lower process risk

Adopting this indexable insert reduces machine downtime and simplifies tool management thanks to its indexable nature and robust grade. The combination of reduced cutting forces and a sharp edge lowers power draw and thermal loading at the cutting zone, which helps to maintain dimensional accuracy over longer runs. The insert is particularly suited to finishing passes on steel where high surface integrity and tight tolerances are required, supporting leaner workflows and more predictable part quality with fewer interventions.

FAQ

What materials is this insert intended for? The NS9530 grade is formulated as a finishing grade for steel; the insert is optimised for continuous turning of steel components.

How does the 0.8 mm corner radius affect surface quality? A 0.8 mm corner radius offers a compromise between edge strength and fine surface finish, enabling improved surface integrity on finishing passes with the TNGG220408 NS9530 insert.

Is the insert reversible or single-use? The triangular design is double-sided, allowing indexing to a fresh cutting edge and extending the service life per insert.

Which holders are compatible with this ISO insert? Compatibility is determined by ISO form, relief angle, tolerance class, fastening method, size and thickness; the TNGG220408 insert fits ISO-standard triangular turning holders that match these parameters.

Can this insert be used for interrupted cuts? The NS9530 finishing grade is optimised for continuous cuts and small depths of cut; for heavy or highly interrupted machining, a more robust grade may be preferable.
