High-quality finishing with reduced cutting forces

The combination of an uncoated cermet substrate and the NS9530 grade prioritises edge sharpness and surface integrity, making this insert ideal for finishing passes on steel. Cermet combines ceramic hardness with metallic toughness; in practice, this means a sharp cutting edge that sustains low cutting forces and produces a smoother surface finish, particularly in continuous turning where chatter and edge wear are critical. The result is less rework and a reliable dimension and appearance on each component.

Secure indexing and compatibility for stable machining

Designed as a 60° triangle with a cylindrical hole and double-sided geometry, the insert offers economical indexing: each side provides multiple usable edges, reducing downtime for tool changes. The ISO-standard format simplifies replacement and toolholder matching, with compatibility determined by shape, clearance angle (0°), tolerance class, mounting method, size and thickness. Features such as the corner radius 0.8 mm and plate thickness 4.76 mm help to balance edge strength and finish when paired with a suitable holder and clamping system.

Practical integration into turning workflows

Use this insert for external and internal turning where a finishing grade is required; select the double-sided chipbreaker to suit the rigidity of the setup and the intended cut depth. The insert is intended to be combined with a matching ISO external holder or boring bar, plus the appropriate shim/clamp set and replacement screws for secure seating. Specifying NS9530 for finishing operations typically improves process stability and repeatability, supporting higher productivity and consistent part quality across batches.

FAQ

What materials is this insert suited for?
The NS9530 finishing grade is formulated for machining steel; the TNGG 220408 insert performs best in continuous finishing cuts and small depths of cut on steel workpieces.

How many cutting edges are available per insert?
The triangular, double-sided design provides multiple usable cutting edges per insert; the cylindrical hole secures the insert for reliable indexing and repeatable re-clamping.

What does the 0° clearance angle mean for machining?
A 0° clearance angle indicates the insert geometry is neutral in relief; selection of holder geometry and cutting parameters will determine contact conditions and should be matched to machining rigidity.

How should the insert be clamped in a holder?
Compatibility is ensured by matching form, clearance angle, tolerance class, mounting style, size and thickness; use an ISO-compatible external holder or boring bar with the correct shim/clamp set and screws.

Which chipbreaker should be chosen for a given application?
Select the chipbreaker and grade according to the workpiece material, the machining strategy and the rigidity of the setup; NS9530 is a finishing grade and pairs with chipbreakers for small cuts and fine surface requirements.
