TNGG 220404 NS9530 Wendeplatten - Tungaloy

High-precision finishing of steel parts benefits from the NS9530 uncoated cermet grade and a fine 0.4 mm corner radius, which together deliver low cutting forces and consistently superior surface quality; order the insert directly via Metav Werkzeuge or consult our advisors for suitability and delivery.

TNGG220404 NS9530 Tungaloy turning insert — ISO triangular, 60° geometry

The TNGG220404 NS9530 is an ISO triangular turning insert designed for finishing operations in external and internal turning, providing a fine cutting edge and predictable results.

• ISO triangular insert, 60° cutting geometry
• NS9530 uncoated cermet finishing grade
• 0.4 mm corner radius for fine surface finish
• Double-sided chipbreaker with cylindrical hole

Precise finishing for steel with predictable results

The insert is furnished in the NS9530 uncoated cermet grade, a finishing specification engineered for low-friction cutting and low cutting forces, which reduces tool-induced vibration and helps achieve a superior surface finish on steel components. The 0.4 mm corner radius supports stable, small-depth cuts and is particularly effective in continuous cutting conditions, where the sharp edge and cermet wear characteristics preserve dimensional accuracy. This combination translates into fewer rework cycles and more predictable part quality in batch production.

ISO compatibility for reliable tool set-up

Built to the ISO plate family and supplied as a triangular insert with a 60° main cutting geometry, the design ensures repeatable clamping and simple matching to corresponding holders. The plate has a nominal size of 22 mm and a plate thickness of 4.76 mm, and it is supplied with a cylindrical hole for secure fixing. Compatibility with a toolholder is governed by form, relief angle, tolerance class, fastening method, size and thickness; adherence to ISO norms simplifies tool inventory management and reduces set-up time on the shop floor.

Productivity and handling advantages in finishing operations

The double-sided chipbreaker offers reliable chip control across the profile while maximising the number of usable edges through indexing; this indexable insert format lowers per-edge cost and minimises downtime for changes. Suited to both external and internal turning, the grade performs best in finishing passes with small feed and depth parameters, where the sharp cutting edge and cermet microstructure produce consistently fine results. In short runs or high-mix environments, the insert’s predictable wear behaviour supports stable cycle times and repeatable surface quality.

FAQ

What materials is this insert best suited for?
The TNGG220404 NS9530 insert is a finishing grade optimised for steel; the uncoated cermet composition is selected to produce low cutting forces and fine surface finishes on continuous turning passes.

Is this insert compatible with standard ISO triangular holders?
Yes, the plate follows ISO geometry (220404) and its compatibility depends on matching form, relief angle, tolerance class, fastening method, size and thickness to the holder.

How many usable edges are available before regrinding or replacement?
The triangular, double-sided format allows multiple indexings; actual edge count per insert depends on the holder set-up and whether both sides are utilised.

Does the insert have a chipbreaker and how does it affect performance?
The insert features a double-sided chipbreaker designed to improve chip control during finishing, supporting stable cutting and consistent surface quality.

Can this insert be used for internal turning as well as external turning?
Yes, the design and grade are suitable for both external and internal turning operations, particularly in finishing passes with small depths of cut.
