TPGT 16T304 NS9530 Tungaloy turning insert – triangular ISO, 0.4 mm radius, finishing grade

The TPGT16T304 NS9530 turning insert is a triangular ISO-standard insert engineered for finishing steel in continuous turning operations, offering a sharp edge and low cutting forces for superior surface quality

• ISO-standard triangular insert for consistent clamping
• Uncoated cermet NS9530 for high surface finish
• 0.4 mm corner radius for precise finishing
• Cylindrical hole with single-sided countersink

Precision finishing with an uncoated cermet grade

The NS9530 designation denotes an uncoated cermet developed for fine finishing of steel, combining a sharp cutting edge with low cutting forces to minimise workpiece distortion and achieve an excellent surface finish. Cermet is a ceramic–metal composite that maintains a keen edge at moderate cutting speeds, which makes it particularly suitable for continuous cuts and small depths of cut where surface integrity is the priority. In practice, this means fewer secondary operations and more consistent part quality when a smooth finish is required.

Predictable clamp and holder compatibility for reliable production

Compatibility with the toolholder is determined by insert form, 11° clearance, tolerance class, fastening method, size and thickness; adherence to ISO standards ensures predictable fitting and repeatable results. The triangular geometry with a 0.4 mm corner radius provides a defined contact pattern in the pocket, while the cylindrical hole combined with a single-sided countersink (40°–60°) secures the insert against rotation and micro-movement. A stable clamp arrangement, accurate tolerance match and the correct chipbreaker choice deliver reproducible tool life and reduced set-up time in series production.

Application advice and machining benefits for finishing turning

When applied as intended for finishing, the TPGT16T304 NS9530 insert gives low cutting forces and an excellent as‑cut surface, reducing the need for polishing. Best results occur with small depths of cut and continuous feed; for interrupted cuts or heavy roughing, a different grade or geometry is preferable. The single-sided chipbreaker supports chip control for the targeted material and machining mode, aiding swarf evacuation and protecting the cutting edge. Using ISO‑compliant holders and correct torque for the clamp screw preserves the insert seat and maintains repeatable accuracy in multi-shift production.

For finishing operations where surface quality and low cutting forces matter, specify the Tungaloy NS9530 insert via Metav Werkzeuge or contact our technical consultants for a tailored recommendation.

FAQ

What steels is this insert optimised for? The TPGT16T304 NS9530 insert is optimised for machining steel in finishing operations, offering low cutting forces and a high-quality surface finish.

Can this insert be used for roughing or interrupted cuts? This grade is a finishing sort; for heavy roughing or interrupted cuts, a tougher grade or different geometry is recommended instead of the NS9530 finishing insert.

Which holder characteristics must match the insert? Compatibility requires matching the insert form, clearance angle (11°), tolerance class, fastening style, size (16 mm) and thickness (3.97 mm) to ensure secure clamping and repeatable performance.
