TPGN 160308 NS9530 – ISO turning insert (triangular), finishing grade by Tungaloy

TPGN160308 NS9530 is an ISO triangular turning insert intended for fine finishing in external and internal turning applications, designed to deliver low cutting forces and excellent surface quality.

• ISO triangular insert for standard holders
• Uncoated cermet NS9530 for high surface finish
• 60° geometry for precise turning
• 0.8 mm corner radius for fine finishing

Superior finishing performance with NS9530

The insert is built on an uncoated cermet grade, NS9530, specifically formulated as a finishing sort for steel. This composition provides a sharp cutting edge and reduced friction compared with some coated grades, which translates into lower cutting forces and a cleaner, more consistent surface finish during continuous cuts. For operations where minimal tool marks and tight surface tolerances are critical, the combination of cermet substrate and a fine edge geometry supports predictable, repeatable results and can reduce rework or downstream polishing. The finishing behaviour of this grade also helps to maintain dimensional integrity when small depths of cut are used.

Reliable ISO fit and controlled geometry for process stability

The insert follows ISO designation standards, so form and tolerance match established holder interfaces; compatibility is determined by the insert shape, 11° clearance angle, tolerance class, fastening method, size and thickness. The triangular form with a 60° included angle and a corner radius of 0.8 mm is particularly suited to finishing passes where controlled contact and gentle entry reduce vibration and leave a consistent profile. The 3.18 mm plate thickness contributes to rigidity while the absence of a centre hole simplifies clamping arrangements in holders designed for solid-pocket retention. Understanding these geometric parameters enables straightforward selection of an appropriate external holder or turning bar to secure cutting stability and repeatable chip formation.

Practical system guidance and application advantages

The cutting system is composed of the indexable insert, a matching external holder or boring bar, a seating pad/clamping kit and replacement screws; ensure holders are matched to the insert’s ISO outline and thickness for correct clamping. As a finishing grade, the insert excels in both external and internal turning where continuous cutting and modest feed rates are used. Selection of a suitable chipbreaker or a different grade should be considered when encountering interrupted cuts or heavier machining requirements. The base material for the substrate is carbide, offering the balance of toughness and edge integrity needed for repeatable finishing tasks. Using this configuration reduces the likelihood of built-up edge and supports consistent productivity across series production.

FAQ

What materials is this insert suited for?
The TPGN160308 NS9530 insert is a finishing grade developed for steel; its uncoated cermet composition provides a sharp edge and low cutting forces particularly favourable for continuous finishing cuts on steel.

How does the NS9530 grade affect surface finish?
NS9530’s uncoated cermet structure promotes a fine cutting edge and stable cutting behaviour, so the insert produces consistently high surface quality when used with appropriate feeds and depths of cut.

Which holders are compatible with this ISO insert?
Compatibility depends on the holder’s form, clearance, tolerance class, fastening method, size and thickness; choose an ISO-compatible external holder or boring bar designed for triangular TPGN 160308 geometry and 3.18 mm thickness.

Is this insert suitable for interrupted cuts?
As a finishing sort, the insert performs best in continuous cuts; for interrupted cutting or heavy roughing, consider a different chipbreaker or a tougher grade better suited to variable engagement.
