TNGG160404 NS9530 triangular ISO turning insert for finishing (Tungaloy)

The TNGG160404 NS9530 is an ISO-standard triangular turning insert engineered for fine finishing of steel in continuous-cut operations.

• ISO triangular insert, 60° cutting geometry
• Uncoated cermet grade NS9530 for high surface finish
• Low cutting forces for continuous finishing cuts
• Cylindrical hole and 0.4 mm corner radius

Consistent fine finishing with an uncoated cermet grade

The insert is specified as an uncoated cermet in grade NS9530, developed for finishing of steel where a sharp cutting edge and low cutting forces are required. Cermet combines ceramic and metallic phases to provide a stable edge that resists built-up edge formation; this results in a high surface finish and predictable performance on continuous cuts and small depths of cut. The use of a finishing-grade substrate reduces friction at the cutting zone and supports repeatable part tolerances on turned components.

Designed for reliable holder compatibility and secure clamping

As an ISO turning insert, compatibility with the toolholder is governed by the insert form, relief angle 0°, tolerance class, fastening method, size and thickness. The triangular geometry with an included angle of 60°, a cylindrical hole and double-sided chipbreaker ensure the insert seats and clamps securely in standard external holders or boring bars. The system typically comprises the ISO insert, a matching outer holder or boring bar, a locating shim/clamping set and replacement screws; correct matching prevents movement, improves repeatability and simplifies index changes during production.

Small corner radius for fine detail and low cutting force demands

The corner radius 0.4 mm balances surface finish and edge strength for finishing passes: a smaller radius lowers required feed forces and produces finer surface textures, while still offering adequate edge stability for continuous feeds. The 0° relief angle yields a neutral cutting geometry that is well suited to delicate finishing cuts on steel. For machinists this means more consistent part appearance and fewer secondary processes; for production planners it translates into reduced cycle-time variability and improved first-pass yield when the right grade and chipbreaker are selected.

Operational advantages and application focus

Specified for turning operations, this ISO insert targets customers requiring excellent surface quality on steel components with small depths of cut and continuous cutting conditions. The double-sided chipbreaker offers two usable cutting edges per seat, extending effective edge life and improving cost-efficiency. Where higher process stability and predictable edge behaviour are priorities, the combination of the NS9530 cermet grade and the triangular ISO format supports smooth chip formation and reduced vibration during finishing, which is particularly beneficial for serial production and precision parts.

FAQ

What materials is this insert suited for?
The TNGG160404 NS9530 insert from Tungaloy is intended primarily for finishing of steel; the NS9530 cermet grade is optimised for low cutting forces and high surface finish on continuous cuts.

How does the 0° relief angle affect performance?
A 0° relief angle gives a neutral cutting geometry that stabilises the edge in finishing passes, reducing cutting forces and supporting fine surface results when using the TNGG160404 insert.

Can the insert be used in standard ISO external holders?
Yes; the ISO designation and triangular form ensure compatibility with matching external holders and boring bars when the holder matches the insert’s form, size, thickness and clamping method.

How many usable edges does the insert offer?
The insert features a double-sided chipbreaker, providing multiple indexed cutting edges to extend service life before replacement.

What role does the corner radius play for surface finish?
The 0.4 mm corner radius balances edge strength and surface quality: it reduces feed forces for finer finishes while maintaining sufficient edge robustness for continuous finishing operations.
